The Board
The schematic is loosely based on our panda jungle v2, a development and debugging board for comma devices and pandas. This version includes:
- 12V DC input with onboard 5V and 3.3V supplies
- Four OBD-C device ports with individually controlled power and current monitoring
- Four CAN-FD transceivers and ignition simulation circuitry
- A USB hub and USB-C host connection
- A microcontroller and microSD card slot
- A push button and status LEDs
