WAS is now very easy, use TM171 or BNO85 as WAS sensor

“PS0” must be connected to “VCC_3V3”. In your case, a solder joint on the jumper associated with PS0 will do that job. It’s a 3.3V-only board, so be sure to use a Serial-USB-cable with 3.3V supply output. When using a simple cable like this, just daisy-chain a red LED in the supply line of the cable. Connection is like that: “GND”: GND (often a black wire) “SDA/MISO/TX”: RxD of cable (often a white wire) “VCC_3V3”: supply like descibed above (often a red wire, mind the voltage!) That’s all.…
