Car: common questions

What microcontroller does the Car use?

The Car is built around the ATmega328P-A, from the AVR/Arduino family.

How big is the Car PCB?

The Car measures 50 × 67 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Car?

94 components, from 43 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Car design files?

From the le-flav-b/VEMAR repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Car design in my own project?

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

Can I test firmware for the Car 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.
