# ESP32 (Arduino) Based Bicycle Computer with GPS and SD logging

This is still work in progress but mostly functional this far.
The code and mechanical aspects of the project definitely work well enough for a daily usage scenario.
_Documentation isn’t available yet, I’d recommend anyone to start this project who already has a decent understanding of electronics.
See the code for pin-definitions and / refer to the schematic in the pcb folder on GitHub_

Quick overview:
- GPS Speedometer and other data such as altitude, traveled distance and time
- 128x64 LCD
- RTC DS3231
- Temperature and Humidity Sensor HTU21D
- LDR for backlight adjustment
- Micro SD for logging your trips
- Charging over Qi Wireless charging
- One user-button
- 2x 14500 LiFePO4 Battery

Print the necessary files and build the circuit.
