2 Hardware involved
2.1 WMDA-119AN Module
The following figure shows the TX board, which has 4 transmitting antennas. Each
antenna has a matching push connector (marked SW-1 to Sw-4) for conducted
measurements.
The board has a UART port located on the top of the board (marked J2) for
communication of the Baseband chipset (marked U1). The board has a UART port
located on the Top of the board (marked J501) for communication of the MCU chipset
(marked U501).
The board has a Power connector located on the top of the board (marked J702) for the
5V power supply.
