Rc car remote: common questions

What microcontroller does the Rc car remote use?

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

How big is the Rc car remote PCB?

The Rc car remote measures 120 × 48 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rc car remote?

31 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rc car remote design files?

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

Can I use the Rc car remote 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 remote 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.
