A couple of months ago, I wanted to experiment with LoRa modules. I started with a breadboard, two AI-Thinker Ra-02 LoRa modules, Nokia displays and ATmega328 boards. After a couple of experiments, I designed a tiny board, my first LoRa pager.

I’ve been wanting to experiment with LoRa for a while – this looks like an interesting and well done project.
