Hi @beegee and @carlrowan ,
Would like to share my new project.
I call it RAK3172MiniBoard, with the RAK3172 module as main/unique controller.
With this board I intend to implement LoRaP2P and LoRaWAN connections. Besides interfacing with different inputs, sensors and external memory.
Thank you for the great support you both have given so far!
