Acconeer XB112 Radar Breakout Board is designed to make the interfaces from the XM112 module accessible for evaluation and debugging. The XB112 additionally enables flashing of the XM112 via USB-UART or SW-DP. The XM112 connects to the XB112 via a board-to-board connector on the top side of the PCB.
In addition to the board-to-board connector for the XM112, the XB112 incorporates two USB connectors, two 2×5 pin headers, and one not mounted 2×20 pin header. Two buttons are to be used when flashing via USB-UART. The buttons control the pins “ERASE” and “NRST” on the MCU on the XM112. A dual LDO, a switched power regulator, and two FTDI chips that convert USB into UART and SPI are also available on the board.
