# RNode Firmware - Mees Electronics Edition
This version of the RNode firmware is made to add support for the E22-400M33S LoRa module. With an output power of 33 dBm this module is suitable for ham radio applications.
This is a copy of the community maintained fork of the open firmware which powers RNode devices found on [https://github.com/liberatedsystems/RNode_Firmware_CE](https://github.com/liberatedsystems/RNode_Firmware_CE). The copy has been created to add support for hardware designed by [Mees Electronics](https://meezenest.nl/mees). The original repository by Mark Qvist can be found [here](https://github.com/markqvist/RNode_Firmware).
The first new board is a combination of a Waveshare ESP32 S3 Pico and an Ra-02 SX1278 LoRa transceiver. See [./Documentation/HOWTO-change-firmware-and-compile-it_MeesElectronics.md](https://git.meezenest.nl/marcel/RNode_Firmware_CE/src/branch/master/Documentation/HOWTO-change-firmware-and-compile-it_MeesElectronics.md) for more information about adding a new board to the code.
Support is added for **ESP32 S3** boards with either an **SX1278** or an **SX1268** LoRa module. It is tested with a **Waveshare ESP32 S3 Pico** and a **LilyGO T7-S3 ESP32-S3 Development Board**. But it is expected to work with all ESP32 S3 boards which expose the proper GPIO pins. LoRa modules that are tested are the **Ra-02 SX1278** transceiver and the **E22-400M33S SX1268** transceiver. See [./Documentation/HOWTO-change-firmware-and-compile-it_MeesElectronics.md](https://git.meezenest.nl/marcel/RNode_Firmware_CE/src/branch/master/Documentation/HOWTO-change-firmware-and-compile-it_MeesElectronics.md) for more information about adding a new board to the code.
The Waveshare firmware also works on the LilyGO T7-S3 ESP32-S3 Development Board. And it is expected to work on all ESP32-S3 boards which expose the proper GPIO pins.
