3D-printed enclosure for the GPS tracker

A complete motorcycle GPS tracking system built around the LilyGO T-SIM7000G — a compact board combining an ESP32 microcontroller with a SIM7000G cellular/GPS modem, an SD card slot, and an 18650 battery holder. The tracker sends GPS coordinates, speed, temperature, and battery voltage to a self-hosted server over 2G/NB-IoT/CAT-M cellular.

The MotoTracker web dashboard runs on a Raspberry Pi (Apache + PHP + MySQL) and displays the day's route on an interactive Leaflet map, color-coded by speed. Rides can be replayed in real time or exported as GPX files for use in Strava, Garmin Connect, or other apps.

Firmware Features

Live mode: GPS always on, sends 1 point/second via HTTP GET with keep-alive TCP connection
Batch mode: deep sleep 60 s between fixes, RTC memory batches 5 points per wake — low power
SD offline buffer: up to 100 000 points (~27 h at 1 pt/s) stored on SD when network is unavailable; auto-recovered on reconnect
Battery protection: auto-sleeps below 3.3 V to prevent over-discharge
Compact HTTP protocol: short parameter names (k, v, la, lo, s, t, h, b, ts) to minimise cellular overhead

Dashboard Features

Leaflet map: route drawn as a polyline colour-coded green→red by speed
Ride stats: total distance, duration, average and max speed, temperature, battery voltage
Ride replay: animated playback with adjustable speed (1×–20×)
Ride history: list of the last 50 rides with date, point count, and duration
GPX export: download any day's ride as a standard GPX track file
Live tracking: auto-refreshes every 2 s when viewing today's date
