Meshtastic is one of those projects that sounds too good to be true. It’s an open-source mesh network that lets you send encrypted text messages and share GPS locations over LoRa radio, with no cell towers, no Wi-Fi, and no subscription, and all you need is a cheap device to join. I’d been watching it gain traction for a while, especially as more cities started building out their own community mesh networks, and I figured it was time to try it for myself. The Elecrow Thinknode M5 seemed like the perfect entry point, arriving pre-flashed with Meshtastic firmware and ready to go out of the box.
