Trail Mate open-source firmware leverages Meshtastic and MeshCore for ESP32 off-grid handhelds
vicliu624's Trail Mate is an open-source firmware for off-grid communication and GPS coordinates sharing, leveraging the Meshtastic, MeshCore, and other projects, and designed for ESP32 handhelds such as LILYGO's T-LoRa Pager or M5Stack's Tab5 with a LoRaWAN module. The Trail Mate firmware provides a fixed north-up GPS map, direct LoRa text messaging through Meshtastic or MeshCore mesh networks without relying on a smartphone, and prioritizes stability, efficiency, and interoperability over feature density. Trail Mate user interface highlights: Simple main menu with four icons: GPS, LoRa chat, tracker, and system utilities. GPS map Fixed North-Up map orientation (no rotation) Fully offline map rendering from SD card tiles (png/jpg files) Three switchable base layers: OSM / Terrain / Satellite Optional contour overlay for terrain shape awareness Real-time position marker for the current GPS fix Discrete zoom levels optimized for embedded systems Simple breadcrumb trails for path awareness Fast in-page layer switching via
Plai is a nicely polished #meshtastic app for #M5Stack #cardputeradv. I dig.
If you're a fan of dev boards from #Lilygo or #M5Stack, Launcher by bmorcelli is a simple but truly glorious piece of software.
Launcher makes it easy to switch between firmwares without flashing from a computer each time. When I get a new unit from M5, Launcher is usually my first stop.
Joebob sez check it out.
