Introduction

For one of my current projects, I'm writing a communication system using the Adafruit LoRa Radio FeatherWing - RFM95W 433 MHz module from RadioFruit. I had a lot of trouble getting the module to cooperate. It took me way longer than I care to admit just to get the first sign of life from the module, so I'm writing this in hopes to spare others from spending too many hours making the same mistakes I did.

What I will cover

As mentioned in the introduction, I used the Adafruit LoRa Radio FeatherWing - RFM95W 433 MHz module. I imagine other frequencies as well as any other Featherwing radio in the RFM95x and RFM69x series should work just as well. I will split this into three parts. First I'll cover how I got it to work on an Arduino UNO, then move on to the ESP32C3 DevKit-02 board using the Arduino IDE, and finally I'll cover how to use the FeatherWing with the ESP32C3 DevKit-02 board using Rust (which is the language used in the project) and a c
