The PCB was designed in KiCAD and manufactured by OSHPark. It's essentially a giant shield for an Arduino Mega that drives many Power MOSFET devices, and conditions the inputs from the car. It also has many connectors for illuminated pushbuttons.
Many through-hole components were used for ease of assembly, and overall design simplicity.

Controller-Electrical-Schematics: common questions
What microcontroller does the Controller-Electrical-Schematics use?
The Controller-Electrical-Schematics is built around the ARDUINO_MEGA_SHIELD, from the AVR/Arduino family.
How big is the Controller-Electrical-Schematics PCB?
The Controller-Electrical-Schematics measures 181.7 × 127.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Controller-Electrical-Schematics?
216 components, from 34 distinct parts. The full bill of materials is listed on this page.
Where can I download the Controller-Electrical-Schematics design files?
From the mk4-dd/Controller-Electrical-Schematics repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Controller-Electrical-Schematics design in my own project?
The repository has no license, so all rights stay with mk4-dd. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Controller-Electrical-Schematics without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
