Car Hacking PCB and firmware for a USB to CAN interface, with support for 4 CAN transceivers and an optional NEO-MP8 GNSS module.
README
Raccoon
PCB and firmware for a USB to CAN interface, with support for 4 CAN transceivers and an optional NEO-MP8 GNSS module. The design is a reverse-engineering of comma.ai's Black Panda. It uses a modified version of the panda firmware/SDK.
Usage
For self-driving, it is better to buy a red panda from comma.ai. In addition to getting a more reliable product, you'll be supporting open-source software and a really smart group of people.
Header
The design uses an automotive-grade Deutsch header, which eliminates the need for a switching relay. Feel free to replace this with something else. If you want to use "ODB-C" you'll need to use pins C0/C3 (inputs), C10/C11 (outputs).
To use the deutsch header, you'll need a crimper and some parts:
- 1 DTM13-12A or some variant of the header. This needs hand-soldered.
- 1 DTM06-12S, the male connector
- 1 WM-12S, a wedgelock
- 12 Crimpable Sockets
Hand-Soldered Components
There are a few components that need purchased and hand-soldered to make the board work.
GPS
If you order the board as-is from JLCPCB, you can use it with or without GPS.
To use it with GPS, you'll need to hand-solder/install these parts:
- 1 NEO-MP8-2
- 1 W2H15C4738AT1A, a feedthrough capacitor for the GPS antenna.
- 1 Active GNSS Antenna. See Table 7 in the NEO-M8P guide for recommendations.
To use it without GPS, just jump the through-holes labeled NO_GPS. This will tell the firmware to ignore the GPS.
Warning
The board design is untested because of the chip shortage. Use at your own risk.
