Module LoRa (433MHz)


This tutorial will show how to use M5 BASIC host and Module LoRa (433MHz) to implement LoRaWAN470 gateways and nodes and to communicate with TTN , we put the firmware in Burner


LoRa (433MHz) is a LoRa communication module in the M5Stack stack module series (working frequency is 433MHz). A certain expansion space is reserved on the module, which defeats you for more functional design. For wireless communication or projects with more customized elements, the LoRa (433MHz) module will be a suitable choice.
