Technical Details

Radio & MCU

LoStik for LoRa® wireless networks uses a RN2903 (US) or RN2483 (EU) depending on what ITU region you are in; if you are unsure which version you need check out the frequency plan.

LoStik uses a simple ASCII interface. You can configure it and send commands over serial / COM port. Microchip provides a detailed command reference RN2903, RN2483

The radio can be used in packet mode sending packets between nodes. This provides simplex, single-channel communications. If you want to speak LoRaWAN you need a gateway or access to one. Some countries in Europe provide nation-wide coverage.

If you want to tinker with the MCU directly it is possible (but not necessary) to write your own firmware. There is an unpopulated ICSP header and the onboard MCU is a PIC18LF46K22 and Microchip supplies LoRaWAN libraries for use with MPLab.
