Adding LoRaWAN to Feather RP2040

Post by nbogdan »

Starting with Feather RP2040, I want to use a transceiver RFM95W for LoRa communication with a gateway.

The wirings are shown for Feather M0 and Raspberry Pi Pico below, but I still need the pin wirings for a Feather RP2040. I have filled in some, but the "??" fields are either inconsistently documented or lacking documentation. Anyone have any pointers or corrections here?

The feather-rp2040 is a feather, which means it follows adafruit’s layout for pin assignments. So you should be able to use the same pins as the feather-m0 examples.

For the four ?? Pins in your question, on the photo you included, looking at the top of the feather-rp2040 (the side with the USB-C connector and the chips) the Vin is named 3.3v, there are 2 pins, use either one. The SCK pin is labeled “SCK”. The MOSI pin is labeled “MO”, the MISO pin is labeled “MI”. Wire those to the SCK, MOSI, and MISO pins on your RFM95 board. SCK to SCK. MOSI to MOSI, MISO to MISO. And wire 3.3v to Vin.
