Vehicle Accessory Controller: common questions

What microcontroller does the Vehicle Accessory Controller use?

The Vehicle Accessory Controller is built around the ATMEGA328P-M(32QFN_MLF), from the AVR/Arduino family.

How big is the Vehicle Accessory Controller PCB?

The Vehicle Accessory Controller measures 61.4 × 75.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Vehicle Accessory Controller?

74 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Vehicle Accessory Controller design files?

From the EmbeddedDesign/VehicleAccessoryController repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Vehicle Accessory Controller design in my own project?

The repository has no license, so all rights stay with EmbeddedDesign. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Vehicle Accessory Controller 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.
