I’m trying to run a microphone into an ExpLoRaBLE board, but none of the example codes are helping to identify where the PDM/I2S can interface. Does it have PDM or do I need to get a different board?
Looks like the NM180100 module on the ExpLoRaBLE has PDM/I2S functionality but I don’t know if the pins for that are broken out. There’s a data sheet for the module but they don’t specify what pins to use, you’d need to do some digging to see if the pins are available and broken out on our board.
You can find more info on the module at the link below.
