The breakout board provides an interface for the XM122 IoT module so that it can easily be flashed and debugged. It also has an internal power supply as well as a battery holder to be able to develop battery driven IoT applications.For More information please read:•XM122 Data Sheet•XM122_XB122 User Guide2 XB122 Breakout Board2.1 OverviewThe XB122 breakout board for the XM122 module is designed to make the interfaces from theXM122 module accessible for evaluation and debug. With the XB122 breakout board, flashing ofXM122 can be done either via the USB to UART interface or the SWD/JTAG interface. The XM122 is connected to the XB122 via a board-to-board connector on the top side of the XB122 PCB.In addition to the board-to-board connector for the XM122, the XB122 comprises a USB micro B receptacle, a 2x5 pin header and a 2x10 pin header. There are two buttons on the XB122, marked DFU and NRST. The NRST button is connected to the reset pin of the nRF52840 MCU and the DFU isu sed for “Device Firmware Update”. An LDO, a CR2477 coin cell battery connector and a FTDI chip that converts USB into UART is also available on the board.The picture below shows the XB122 radar module breakout board. The leftmost picture shows the front side of the XB122, with the board-to-board connector for the XM122 module, and the rightmost picture shows the reverse side of the XB122.The picture below shows the dimensions of the XB122.The thickness of the PCB is 0.8mm +- 0.2 mm. The diameter of the holes is 3.2mm. The block diagram of XB122 is found in Figure 1 below.Figure 1. The block diagram of XB122.2.2 PowerThe XB122 is powered via the USB connector. The USB 5V power domain supplies the USB-UART chip (U1). If the USB-UART interface is not used, a dedicated USB charger can be used.When the LED D1 on the XB122 is lit, the USB-UART chip is powered and ready to use. If SW1 is set to “USB” it a lso means that XM122 is powered and ready to use (if connected to the board-to-board connector on the top side of XB122). Alternatively, if SW1 is set to “BATTERY”, the XM122 is powered from a CR2477 battery. However, the internal XB122 circuitry is still powered from the USB so that the battery power is only dedicated to the XM122 module. A CR2477 battery is not provided with EVK.The 5 V from the USB connector is supplied directly to the USB-UART chip 5V input. It also powers an LDO (Low Drop-Out power regulator) that generates 1.8V for the USB-UART chip GPIOs.The ENABLE signal of the power switch (U2) is controlled by GPIOs on the USB-UART chipFT230XS. As shown in Figure 2, t he GPIOs “CBUS0” and “CBUS1” are connected to a NAND gate (U3) which in turn enables the power switch. “CBUS0” is configured as “BCDCHARGER#” and “CBUS1” is configured as “PWREN#” as defaul t.Figure 2. Block Diagram showing the logic control of the Power Switch ENABLE signal.“BCDCHARGER#” will output a logic “0” if a USB Dedicated Charger is detected. This means that the XB122 can be powered from a USB Dedicated Charger if no data is to be sent. “PWREN#” will output a logic “0” as soon as the FT230XS has been configured by the USB host. This prevents excess current being drawn by the XM122 during USB enumeration of FT230XS, since no power will be available for the XM122 until USB enumeration is completed. For details regarding the configuration of FT230XS refer to chapter 2.5.If the USB host on the external processing unit enters suspend mode, PWREN# will be set high and the powerswitch will be disabled. It is therefore important to ensure that the external processor USB host doesn’t enter suspend mo de unintentionally.2.3 ConnectorsUSB (J1)USB is used as power supply for the XB122 and the XM122 as well as for flashing and communicating over UART. USB is connected to the FTDI chip FT230XS which converts the UART interface from XM122 into USB data signals. The pinout of J1 is shown in Table 1.Table 1. The pinout of J1.30 pin board-to-board connector (J3)The 30-pin board-to-board connector is intended to connect the XM122 to the XB122. The pinout is found in Table 2.Table 2. The pinout of J3.1 On XB122, the routing of GPIOs P0.23, P0.21, P0.24 and P0.22 between J3 and J5 has been optimized for SPI interface configuration.2x5 JTAG/SWD pin header (J4)The 2x5 JTAG/SWD pin header (1.27 mm pitch) contains the signals needed for flashing the XM122 MCU via the SWD interface. The pinout matches that of the Cortex 10-pin JTAG/SWD Connector and is found in Table 3.Table 3. The pinout of J4.2x10 pin header (J5)The J5 pin header is a miscellaneous 2x10 pin header (2.54 mm pitch) and provides a connection to the XM122 GPIOs as well as VBAT. The pinout is found in Table 4.Table 4. The pinout of J5.2.4 Switches and buttonsThere is one switch on XB122. SW1 determines if XM122 is powered from the USB 5V power domain or from a CR2477 coin cell battery. In Table 5 the position of the switch and the corresponding power source output is shown.Table 5. The connected terminal of the switch SW1 and corresponding VOUT.There are two buttons on the XB122. SW2 controls the signal “DFU” (Device Firmware Upgrade) connected to XM122 and SW3 controls “NRST” connected to the XM122. In Table 6 the state of the buttons and the corresponding signal states are listed.Table 6. The states of the switches SW2 and SW3.2.5 FTDI FT230XS USB-UART (U1)The FT230XS is a USB 2.0 Full Speed compatible USB to serial UART converter. It is integrated on the XB122 to enable communication with the XM122 UART via USB interface. For details regarding the FT230XS refer to the datasheet [1]. For details regarding how to use the XB122 to communicate with XM122, refer to the XB122_XM122 User Guide.The connections of the FT230XS UART interface pins are described in Table 7.Table 7. The FT230XS UART interface pins.Except for the UART interface there are four GPIOs on the FT230XS. The usage and XB122 default configuration of the GPIOs are listed in Table 8. The GPIOs can be flashed via the USB interface by using the program FTPROG from FTDI. For details, refer to the FT230XS datasheet [1].Table 8. The FT230XS GPIOs.XB122– Product Brief2.6 Electrical SchematicsThe electrical schematics for the XB122 are found on the following pages:Page 13 of 21 Proprietary and Confidential© 2019 by Acconeer – All rights reserved 2020-01-22Page 16 of 21Proprietary and Confidential© 2019 by Acconeer – All rights reserved2020-01-222.7 Component Placement DrawingThe component placement drawing of XB122 is found below.

2)智能化:在高性能硬件的基础上,结合信号采集、无功补偿、联网通讯等先进成熟的 软件应用,可实现精确补偿、智能组网、故障自动排除报警等功能。

3)简易化:一体化的设计,使接线更方便,安装更模块化,生产更简易化;智能化的软 硬件结构,使得在现场使用时无需另行参数设置(包括通讯参数等)就可全智能运行, 智能组网功能可自动组网(多机系统中自动生成主机,可控制其他副机),并具有灵 活的重启复位再组网,故障退网等功能,这都使现场投运更简易化。

完完全全实现了 傻瓜模式。

4)零投化:采用成熟的无功补偿控制技术与电容器复合投切技术,实现了无涌流过零投 切的优点,大大提高了电气使用寿命。

5)多样化:可实现单机运行,多机运行模式,即连即用,系统自动判断组网状态,无需 人工设置。

也可根据需要,配置外接参数显示器,或外接无功补偿控制器,或配电监 测计量终端。

6)小型化:采用紧凑的设计,最大的节省了空间,组成柜体后,在体积,成本,运输等 方面可占据更大的优势。

【摘要】近年来,采用1~3W大功率LED做的灯具逐年增加,其功率可从几瓦到上百瓦。

大功率LED灯具都采用LED串联的结构,用恒流供电,其结构如图1所示。

一般1WLED的工作电流为250~350mA,3WLED的工作电流为600~700mA,电流大的可达900~1000mA。
