This is open source hardware for use with 2016/2017 Honda Accord's with Nidec camera units. Other form factors aren't guaranteed to fit - use at your own risk!

There are two boards in this package:
- The LKAS/ECU Manipulator
- The debug board
To connect the debug board to the LKAS/ECU Manipulator a 15 position 0.1" ribbon cable should be used. This is needed for debugging and testing different scenarios.

Smaller form factor using STM32F1 MCU.
Below is the basic layout and functions of the board.
The board consists of:
- A comparator for-
- Level shifting the 12V to 3.3V to read serial information.
- Level shifting the 3.3V UART to 12V to transmit on the vehicles serial line.
- Two MCP2562FDs for-
- Transmitting/ receiving F-CAN from the vehicle
- Transmitting/ receiving F-CAN to the camera unit.
- Note: Typically this is not used.
- Debug Connector with GPIO and an ADC input
- Teensy 4.0
When mounted the board is slightly larger than the the factory cover can contain.
The board consists of:
- A connection for a potentiometer OR a 3 block terminal for external resistance.
- Note: This is current limited resulting in slightly lower/higher ADC readout values.
- 4 Tactile Push Buttons
- 8 Position DIP Switch
- DIP 1-7 are digital IO
- DIP 8 to onboard POT/ External Pot
- Ribbon cable connector
