Rc car panel: common questions

What microcontroller does the Rc car panel use?

The Rc car panel is built around the ATmega164A-A, from the AVR/Arduino family.

How big is the Rc car panel PCB?

The Rc car panel measures 72 × 59.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rc car panel?

51 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rc car panel design files?

From the qb-creates/rc-car repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Rc car panel design in my own project?

Yes, under the terms of its MIT license, which qb-creates chose for the repository.

Can I test firmware for the Rc car panel 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.
