Software for Your Open Hardware

Arduino firmware that turns the LILYGO T-SIM7000G into a real-time LTE-based GPS tracker reporting position to a self-hosted Traccar server over the cellular network.

Arduino-based GPS tracker for the LILYGO T-SIM7000G that publishes location, battery, signal strength, and sensor readings to an MQTT broker over LTE — with multiple power modes and OTA update support.

Arduino/PlatformIO firmware for the LILYGO T-SIM7080G-S3 that creates a solar-powered, battery-backed NB-IoT remote sensor node publishing GPS location and environmental data to MQTT or cloud IoT platforms — with deep sleep for multi-day battery life.

A phone-inspired LVGL UI firmware for the LILYGO T-Deck Pro that turns the e-paper + LTE handheld into a functional phone interface with cellular modem support, GPS, touch, audio, and a web-based UI built with PlatformIO.

Arduino sketches for using TinkerNav with the TinkerSend Mobile SIM7000 4G module to download RTK corrections from an NTRIP caster over cellular, enabling rover operation in remote areas without WiFi.
