Comet Navigator - Extension with GPS, IMU, CAN, ANT+

Makers & Developers

Hello folks,
I’m a huge bike maniac and nerd so I want to put a PC on my bike.

I want to build an open source bike platform which I named PedalPirat and want to use the amazing pizero_bikecomputer.

To do so I need to build an extension for the comet to use it as a bike computer.

TL;DR of what I want to build:

Module with

  • Nordic nRF54H20
    • Supports ANT+ (soon)
    • CAN
    • USB Host to connect to the Comet
  • u-blox MAX-M10S (GPS)
  • Bosch BHI385 (IMU/Environmental)
  • CAN-Transceiver (to connect to the PedalPirat or E-Bikes)
  • 5 Buttons (to control the Software)
  • USB Hub (?) to connect AI-Cameras
  • Power Delivery to charge the Comet
  • GPIO/I2C/SPI Breakout

I started a repo for the Add-On and will probably update this post in case more people are interested and maybe want to join the development and use it on their bike or for other purposes.
