FPV Lap Timer – Raspberry Pi & Arduino Based Laptime Tracker
Turn your FPV drone races into fully automated events with this lap timer system! Using Arduino/RX5808 modules per drone channel and a Raspberry Pi running RotorHazard, it logs lap times based on 5.8 GHz signal strength. Easy PCB-based setup with jumper-configurable IDs, I²C connectivity, and full documentation — perfect for racers and event organizers alike.

Story
This project automatically records lap times for FPV drone races using Raspberry Pi and Arduino. Each tracked channel uses an Arduino with an RX5808 5.8GHz receiver, connected via I²C to the Pi. The Pi runs the RotorHazard system to log and analyze signal strength per channel and calculate lap times.
The PCB simplifies setup: just wire the I²C pins, 5V, and GND to the Raspberry Pi, set your node ID via jumper switches (1, 2, 4, 8), and you're ready to go. Includes schematic, layout, and comprehensive online documentation.
📌Highlights:
✅ Raspberry Pi with RotorHazard-compatible I²C interface ✅One Arduino + RX5808 per drone channel ✅ Easy node ID configuration with jumpers ✅ Automatic lap time calculation from 5.8 GHz video signal strength ✅ Includes PCB design and 3D-printed case files
