TinyGS

TinyGS turns an ESP32 and a LoRa radio module into a ground station for small satellites. It listens to LoRa satellites passing overhead and sends what it hears to the TinyGS network, where you can see your station on a world map with the packets it caught. Original project by the TinyGS team on GitHub, GPL-3.0. Chipnik hosts the release binaries unchanged so you can flash them from the browser.

Wire an SX1278 or SX1262 module to the board and pick the pins in the web setup page that the station opens on first start. You also need a free TinyGS account; the setup guide in the project wiki explains how to get the login.

Most LoRa satellites use 433 MHz, so a 433 MHz module and antenna catch the most passes.

Firmware files come from the 2603242 release.
