DWM1001-DEV Raspberry Zero UART


I’m trying to get serial communication on DWM1001-DEV on Raspberry-pi Zero. i had some problems with serial communication with GPIO.

right now the tests that i did are:

Connect all GPIOs to pi zero
connect only TX and RX with separate power supply on the board
Desoldering pin J13

connecting the device directly to USB works fine.

could anyone help me on this.
