the module.For the actual diagram drawn to scale,please refer to Figure7.1Physical Dimensions.Figure3:Pin Layout(Top View)3.2Pin DescriptionThe module has42pins.See pin definitions in Table2.For peripheral pin configurations,please refer to ESP32-S2Series Datasheet.Table2:Pin DefinitionsTable2–cont’d from previous page1P:power supply;I:input;O:output;T:high impedance.2By default,IO26is connected to the CS pin of the PSRAM and cannot be used for other functions. 3.3Strapping PinsESP32-S2has three strapping pins:•GPIO0•GPIO45•GPIO46Software can read the values of corresponding bits from register”GPIO_STRAPPING”.During the chip’s system reset(power-on-reset,RTC watchdog reset,brownout reset,analog super watchdog reset,and crystal clock glitch detection reset),the latches of the strapping pins sample the voltage level as strapping bits of”0”or”1”,and hold these bits until the chip is powered down or shut down.GPIO0,GPIO45and GPIO46are connected to the chip’s internal weak pull-up/pull-down during the chip reset. Consequently,if they are unconnected or the connected external circuit is high-impedance,the internal weak pull-up/pull-down will determine the default input level of these strapping pins.To change the strapping bit values,users can apply the external pull-down/pull-up resistances,or use the host MCU’s GPIOs to control the voltage level of these pins when powering on ESP32-S2.After reset,the strapping pins work as normal-function pins.Refer to Table3for a detailed boot-mode configuration of the strapping pins.Table3:Strapping Pins3Pin Definitions4Electrical Characteristics4.1Absolute Maximum RatingsStresses above those listed in Absolute Maximum Ratings may cause permanent damage to the device.These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied.Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.Table4:Absolute Maximum Ratings4.2Recommended Operating ConditionsTable5:Recommended Operating Conditions4.3DC Characteristics(3.3V,25°C)Table6:DC Characteristics(3.3V,25°C)1VDD is the I/O voltage for pins of a particular power domain.2V OH and V OL are measured using high-impedance load.4.4Current Consumption CharacteristicsOwing to the use of advanced power-management technologies,the module can switch between different power modes.For details on different power modes,please refer to Section RTC and Low-Power Managementin ESP32-S2Series Datasheet.Table7:Current Consumption Depending on RF Modes1The current consumption measurements are taken with a3.3V supply at25°C of ambienttemperature at the RF port.All transmitters’measurements are based on100%duty cycle.2The current consumption figures in RX mode are for cases where the peripherals are disabledand the CPU idle.The measurements below are applicable to ESP32-S2,ESP32-S2FH2,and ESP32-S2FH4.SinceESP32-S2FN4R2and ESP32-S2R2are embedded with PSRAM,their current consumption might behigher.Table8:Current Consumption in Modemsleep Mode1In practice,the current consumption might be different depending on which peripherals are enabled.2In Modem sleep mode,Wi-Fi is clock gated.3In Modem-sleep mode,the consumption might be higher when accessing flash.For a flash rated at80 Mbit/s,in SPI2-line mode the

ESP32-WROVER features a4MB external SPI flash and an additional8MB SPI Pseudo static RAM (PSRAM).The ordering information on the two variants of ESP32-WROVER is listed as follows:Table1:ESP32WROVER Ordering InformationFor detailed ordering information,please see ESP Product Selector.For dimensions of the external antenna connector,please see Chapter10.The information in this datasheet is applicable to both modules.At the core of this module is the ESP32-D0WDQ6chip*.The chip embedded is designed to be scalable and adaptive.There are two CPU cores that can be individually controlled,and the CPU clock frequency is adjustable from80MHz to240MHz.The chip also has a low-power coprocessor that can be used instead of the CPU to save power while performing tasks that do not require much computing power,such as monitoring of peripherals.ESP32integrates a rich set of peripherals,ranging from capacitive touch sensors,SD card interface, Ethernet,high-speed SPI,UART,I2S,and I2C.The integration of Bluetooth®,Bluetooth LE and Wi-Fi ensures that a wide range of applications can be targeted, and that the module is all-around:using Wi-Fi allows a large physical range and direct connection to the Internet through a Wi-Fi router,while using Bluetooth allows the user to conveniently connect to the phone or broadcast low energy beacons for its detection.The sleep current of the ESP32chip is less than5µA,making it suitable for battery powered and wearable electronics applications.The module supports a data rate of up to150Mbps, and20dBm output power at the antenna to ensure the widest physical range.As such the module does offer industry-leading specifications and the best performance for electronic integration,range,power consumption, and connectivity.The operating system chosen for ESP32is freeRTOS with LwIP;TLS1.2with hardware acceleration is built in as well.Secure(encrypted)over the air(OTA)upgrade is also supported,so that users can upgrade their products even after their release,at minimum cost and effort.Table2provides the specifications of ESP32-WROVER.Table2:ESP32WROVER Specifications2.2Pin DescriptionESP32-WROVER has38pins.See pin definitions in Table3.Table3:Pin Definitions2.3Strapping PinsESP32has five strapping pins,which can be seen in Chapter6Schematics:•MTDI•GPIO0•GPIO2•MTDO•GPIO5Software can read the values of these five bits from register“GPIO_STRAPPING”.During the chip’s system reset release(power-on-reset,RTC watchdog reset and brownout reset),the latches of the strapping pins sample the voltage level as strapping bits of“0”or“1”,and hold these bits until the chip is powered down or shut down.The strapping bits configure the device’s boot mode,the operating voltage of VDD_SDIO and other initial system settings.Each strapping pin is connected to its internal pull-up/pull-down during the chip reset.Consequently,if a strapping pin is unconnected or the connected external circuit is high-impedance,the internal weakpull-up/pull-down will determine the default input level of the strapping pins.To change the strapping bit values,users can apply the external pull-down/pull-up resistances,or use the host MCU’s GPIOs to control the voltage level of these pins when powering on ESP32.After reset release,the strapping pins work as normal-function pins.Refer to Table4for a detailed boot-mode configuration by strapping pins.Table4:Strapping Pins2Pin Definitions3Functional DescriptionThis chapter describes the modules and functions integrated in ESP32-WROVER.3.1CPU and Internal MemoryESP32-D0WDQ6contains two low-power Xtensa®32-bit LX6microprocessors.The internal memory includes:•448KB of ROM for booting and core functions.•520KB of on-chip SRAM for data and instructions.•8KB of SRAM in RTC,which is called RTC FAST Memory and can be used for data storage;it is accessed by the main CPU during RTC Boot from the Deep-sleep mode.•8KB of SRAM in RTC,which is called RTC SLOW Memory and can be accessed by the co-processor during the Deep-sleep mode.•1Kbit of eFuse:256bits are used for the system(MAC address and chip configuration)and the remaining 768bits are reserved for customer applications,including flash-encryption and chip-ID.3.2External Flash and SRAMESP32supports multiple external QSPI flash and SRAM chips.More details can be found in Chapter SPI in the ESP32Technical Reference Manual.ESP32also supports hardware encryption/decryption based on AES to protect developers’programs and data in flash.ESP32can access the external QSPI flash and SRAM through high-speed caches.•The external flash can be mapped into CPU instruction memory space and read-only memory spacesimultaneously.–When external flash is mapped into CPU instruction memory space,up to11MB+248KB can bemapped at a time.Note that if more than3MB+248KB are mapped,cache performance will bereduced due to speculative reads by the CPU.–When external flash is mapped into read-only data memory space,up to4MB can be mapped at atime.8-bit,16-bit and32-bit reads are supported.•External SRAM can be mapped into CPU data memory space.Up to4MB can be mapped at a time.8-bit,16-bit and32-bit reads and writes are supported.ESP32-WROVER integrates a4MB of external SPI flash and an8MB PSRAM for more memory space.3.3Crystal OscillatorsThe module uses a40-MHz crystal oscillator.3.4RTC and LowPower ManagementWith the use of advanced power-management technologies,ESP32can switch between different power modes.For details on ESP32’s power consumption in different power modes,please refer to section”RTC and Low-Power Management”in ESP32Datasheet.4Peripherals and Sensors4Peripherals and SensorsPlease refer to Section Peripherals and Sensors in ESP32Datasheet.5Electrical Characteristics5.1Absolute Maximum RatingsStresses beyond the absolute maximum ratings listed in the table below may cause permanent damage to the device.These are stress ratings only,and do not refer to the functional operation of the device that should follow the recommended operating conditions.Table6:Absolute Maximum Ratings1.The module worked properly after a24-hour test in ambient temperature at25°C,and the IOs in three domains(VDD3P3_RTC,VDD3P3_CPU,VDD_SDIO)output high logic level to ground.Please note that pins occupied by flash and/or PSRAM in the VDD_SDIO power domain were excluded from the test.2.Please see Appendix IO_MUX of ESP32Datasheet for IO’s power domain.5.2Recommended Operating ConditionsTable7:Recommended Operating Conditions5.3DC Characteristics(3.3V,25°C)Table8:DC Characteristics(3.3V,25°C)Notes:1.Please see Appendix IO_MUX of ESP32Datasheet for IO’s power domain.VDD is the I/O voltage for a particular powerdomain of pins.2.For VDD3P3_CPU and VDD3P3_RTC power domain,per-pin current sourced in the same domain is gradually reducedfrom around40mA to around29mA,V OH>=2.64V,as the number of current-source pins increases.3.Pins occupied by flash and/or PSRAM in the VDD_SDIO power domain were excluded from the test.5.4WiFi RadioTable9:WiFi Radio Characteristics1.Device should operate in the center frequency range allocated by regional regulatory authorities.Target centerfrequency range is configurable by software.2.For the modules that use external antennas,the output impedance is50Ω.For other modules without externalantennas,users do not

HOBBYWING ESC用户手册说明书
0103Specifications04User Guide05ESC Programming06Programmable Items07Troubleshooting & Multiple ProtectionsExternal Capacitor Module (also called Cappack) Wiring (Optional)2• DEO (Driving Efficiency Optimization) Technology greatly improves throttle response & driving efficiency and reduces ESC temperature.• Built-in high-power BEC with output voltage adjustable among 5.2V, 6.0V and 7.4V. The BEC module is separate from other circuits on the ESC, so the normal BEC output can be guaranteed (when issue like burntpower board happens) to allow users to get the aircraft back before crash. (Note: the FLYFUN 130A/160A HV OPTO V5 doesn’t have this function.)• Normal/Soft/Very Soft start-up modes are compatible with regular propeller airplanes and EDF jet airplanes (pls ensure to select the “Very Soft Start-up” mode when using EDF jet airplanes).• Separate programming cable for connecting ESC to a LED program box and allows users to program the ESC anytime, anywhere. (For detailed info, please refer to the user manual of HOBBYWING LED program box.)• Normal/proportional/reverse brake modes (esp. reverse brake mode) can effectively shorten the landing distance for the aircraft. (Note: the FLYFUN 130A/160A-HV-OPTO-V5 doesn’t have this function.)• Multiple protection features like start-up, ESC thermal, capacitor thermal, over-current, over-load, abnormal input voltage and throttle signal loss effectively prolong the service life of the ESC.There are two ways to program the ESC. One way is to program it with a LED program box; the other way is to program it with the transmitter. The ESC has many programmable items, so we recommend usingthe LED program box to do the ESC programming.For the FLYFUN 80A/120A-V5, its BEC load capacity may be insufficient when using high power servos. In that case, we suggest connecting the stock external cappack to the BEC’s output end (i.e. any idlechannel on the receiver *note 1) in parallel. Users can check if the BEC is working in overload condition by the following method: keep moving relevant throttle sticks (that control servos) to start/stop thoseservos and change directions quickly to see if the receiver or flight control system (if exists) will be restarted during the process. If restart occurs, then it means that the sudden load of the electronic systemexceeds the BEC’s output capability and an external cappack is needed.Note 1: if there is no vacant channel on the receiver, then users can connect a short, thick Y cable (as thin, long cable may affect the capacitor’s performance, so we don’t recommend it) to the BEC’s outputwires in parallel.40A · 60A · 80A · 120A130A HV OPTO · 160A HV OPTOUSER MANUALBrushless Electronic Speed Controller1. Brake TypeNormal Brake: After selected this option, the brake function will be activated when you move the throttle stick to the bottom position. In this mode, the brake amount equals to the brake force you’ve preset.Proportional Brake: After selected this option, the throttle range of 20% to 100% (on the transmitter) will correspond to the ESC throttle output of 0% to 100% while the throttle range of 20% to 0% (on thetransmitter) will correspond to the brake force of 0 to 100%.Reverse Brake: After selected this option, the Reverse Brake signal wire (its signal range must be the same as the throttle range) must to be plugged into any vacant channel on the receiver, and you can control themotor direction via that channel. The channel range of 0-50% is the default motor direction, the channel range of 50% to 100% will cause the motor to spin counterclockwise. The channel stick should be withinthe channel range of 0-50% (0 would be better) when the first time you power on the ESC. After the Reverse function is activated, the motor will stop first and then spin in the reversed direction and then increase tothe speed corresponding to the throttle input. Either signal loss, no matter reverse brake signal loss or throttle signal loss during the flight, can cause the throttle signal loss protection to be activated.2. Brake ForceThis item is adjustable from level 1 to level 7. The higher the level, the stronger the braking effect. It’s only effect in the “Normal brake” mode.3. Voltage Cutoff TypeSoft Cutoff: After selected this option, the ESC will gradually reduce the output to 50% of the full power in 3 seconds after the low-voltage cutoff protection is activated.Hard Cutoff: After selected this option, the ESC will immediately cut off the output when the low-voltage cutoff protection is activated.4. LiPo Cells:The ESC will automatically calculate the number of LiPo cells you have plugged in as per the “3.7V/Cell” rule if “Auto Calc.” is selected, or you can set this item manually.5. Cutoff VoltageThis item is adjustable from 2.8V to 3.8V (they are the cutoff voltages for one cell); or you can disable it if necessary.6. BEC VoltageThis item is adjustable among 5.2V, 6.0V and 7.4V.7. Start-up ModeNormal Start-up: After selected this option, the motor will immediately start spinning and then quickly reach to the corresponding speed when you move the throttle stick from bottom position to top position.Soft Start-up: After selected this option, the motor will slowly start spinning and then quickly reach to the corresponding speed when you move the throttle stick from bottom position to top position.Very Soft Start-up: After selected this option, the motor will slowly (slower than in “Soft Start-up Mode”) start spinning and then quickly reach to the corresponding speed when you move the throttle stick frombottom position to top position. We recommend selecting the “Soft Start-up” or “Very Soft Start-up” mode when you are flying an airplane with a big-sized ducted fan. Please ensure to select the “Very SoftStart-up” mode if the diameter of the ducted fan on your airplane is over 90mm.8. TimingThis item is adjustable from 0 degree to 30 degrees.9. Motor RotationThis item allows you to adjust the rotation direction of your motor between CW and CCW.10. FreewheelingThis item is adjustable between “Enabled” and “Disabled”. With it enabled, you can have better throttle linearity or smoother throttle response.Multiple Protections1. Start-up Protection:The ESC will monitor the motor speed during the start-up process. When the speed stops increasing or the speed increase is not stable, the ESC will take it as a start-up failure. At that time, if the throttle amount isless than 15%, the ESC will try to restart automatically; if it is larger than 20%, you need to move the throttle stick back to the bottom position first and then restart the ESC.(Possible causes of this problem: poor connection/ disconnection between the ESC and motor wires, propellers are blocked, etc.)2. ESC Thermal Protection:The motor will “stutter” when the ESC temperature goes above 110℃ to indicate that the ESC thermal protection is activated. If lower down the throttle input to below 60% at this moment, the “stuttering” willdisappear and the ESC will output the corresponding power. The motor will re-start to “stutter” if the throttle input exceeds 60%. In this condition, disconnect the battery first and then re-connect it to the ESC afterthe ESC cools down (the ESC temperature cannot exceed 70℃, otherwise it cannot be started), it will resume the normal operation.3. Throttle Signal Loss Protection:When the ESC detects loss of signal for over 0.25 second, it will cut off the output immediately to avoid an even greater loss which may be caused by the continuous high-speed rotation of propellers or rotor blades.The ESC will resume the corresponding output after normal signals are received.4. Overload Protection:The ESC will cut off the power/output or automatically restart itself when the load suddenly increases to a very high value.(Possible cause to the sudden load increase is that propellers are blocked or the motor and the ESC are out of sync.)5. Over-current Protection:The ESC will cut off the output immediately when the peak current exceeds the regulated value, and then restart to resume the output. If the current continues to go above the regulated value, then the output willbe completely cut off. This protection may be activated by the burnt motor or some others.Note:different ESCs have different default settings, please take the default settingsof each ESC as the standard.)01故障描述电调通电以后不工作，鸣叫报警提示音“哔哔，哔哔，哔哔，哔哔，…...”说明输入的电压不在电调的工作电压之内。
