 Started all over again. This time I succeeded! The Waveshare ESP32 S3 Pico and the Ra-02 SX1278 LoRa transceiver are working as a proper rnode. It took me some time, but now I am happy. See Documentation/HOWTO-change-firmware-and-compile-it_MeesElectronics.md for more information about adding a new board to the code.

 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.
 
+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.

+# What it is
 
 An RNode is an open, free and unrestricted digital radio transceiver. It enables anyone to send and receive any kind of data over both short and very long distances. RNodes can be used with many different kinds of programs and systems, but they are especially well suited for use with [Reticulum](https://reticulum.network).
