# Pizero Bikecomputer (open-source science and GIS app)

> Pizero Bikecomputer is a free, open-source science and GIS app for macOS and Linux. An open-source bike computer with GPS and ANT+ capabilities, based on the Raspberry Pi Zero (W, WH, 2 W) or the Compute Module Zero (CM0). It has 1,278 GitHub stars and is released under the GPL-3.0 license.

Pi Zero Bikecomputer is a GPS and ANT+ bike computer based on Raspberry Pi Zero (W, WH, 2 W). This is the first DIY project in the world integrating the necessary hardware and software for a modern bike computer. It measures and records position (GPS), ANT+ sensors (speed / cadence / power), and I2C sensors (pressure / temperature / accelerometer, etc.). It also displays these values, maps, and courses in real time. In addition, it writes logs to.fit format files.
