TesMuffler Hardware Dongle v1

This repository contains information and manufacturing files for the CANOPi automotive prototyping plattform.

The TesMuffler Hardware Dongle is a baseboard for the Raspberry Compute Module 4 (CM4).

With a TesMuffler Hardware Dongle you have all the ingredients for hacking vehicles and prototyping Software Defined Vehicle functions and applications.

• Compatible with the Raspberry Pi ecosystem thanks to the CM4
• Up to 8GB of RAM and up to 32GB eMMC or any size micro SD card storage
• Integrated SIM card slot and M2 slot to add cellular connectivity
• Can be powered via a vehicle's OBD-2 Port
• STN2120 OBD-II to access vehicle data on OBD (only CAN supported by hardware)
• Two MCP251xFD based CAN-FD interfaces allowing interfacing two vehicle classic CAN or CAN FD busses directly.
• PCF85036A Realtime clock

What you can find here

• Find schematics board renders and BOM lists in ./Component_Documentation/
• You can find GERBER files needed to manufacture the PCB in ./GerberFiles
• Altium Designer EDA project file nn case you want to modify the schematics can be found in ./EDA.

How to setup

If you set up a fresh CM4 that has never been used before in CANOPi you need to update the EEPROM first
