Arduino Micro LoRA/FSK KISS modem and APRS AX.25 digirepeater

Introduction

This project is Arduino Micro LoRA/FSK USB KISS modem and standalone APRS AX.25 digirepeater with RA-01 LoRA module.

Probably, could be easily used with other Arduino boards.

Currently, default radio module is SX1278, such as RA-01/RA-02.

Can be build in two modes:

• As USB KISS LoRA/FSK modem, to be used with Linux AX.25 tools over USB or with APRSDroid or Codec2Talkie applications over USB OTG
• As a standalone LoRA/FSK AX.25 digirepeater

Configure

Update include/config.h with your LoRA modulation settings and module pinouts.

Build

Use platformio to build required configuration for repeater or modem.
