LoRa CHAT

Point-to-point text chat over LoRa on UHF 433MHz — no internet connection or SIM card involved.

I built these as a pair of handheld units that let you chat over LoRa radio without an internet connection or a SIM card. Each one runs on a 2000mAh rechargeable battery and communicates over UHF at 433MHz for long range.

To chat, connect your phone to the unit's own WiFi network and open its built-in page in a browser. Type a message and send it, and it goes out over LoRa to the other unit and shows up on their screen the same way.

A video for this kit is coming soon.
