LoRaWAN FeatherWing for Adafruit Feather

LoRaWAN FeatherWing for Adafruit Feather


Dan Watson documented a new custom FeatherWing he has designed to add the MicroChip RN2483/RN2903 LoRaWAN module to Adafruit Feather:

I have designed some FeatherWings in the past to add a LoRa transceiver module to Feather. I did the LoRa FeatherWing Development Breakout and the LoRa FeatherWing IOX that used the HopeRF RFM95/96(W) modules. The RFM modules are small and cheap, which is great for IoT projects. However, they have a limitation if you want to use them with LoRaWAN: the stack is not implemented in the module, leaving that burden to the microcontroller. The LoRaWAN stack takes a fair amount of code space, and it’s difficult to implement in some 8-bit microcontrollers.
This new FeatherWing uses the RN2483 (868 MHz) or RN2903 (915 MHz) from MicroChip. It’s an excellent module that fully implements the LoRaWAN stack itself. The microcontroller talks to it over USART with a simple command structure to configure it and send/receive messages.
