Rc car: common questions

What microcontroller does the Rc car use?

The Rc car is built around the ESP32-S3-MINI-1, from the ESP32 family.

How big is the Rc car PCB?

The Rc car measures 129 × 79.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Rc car?

85 components, from 39 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 Rc car design files?

From the alaotach/rc-car 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 Rc car design in my own project?

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

Can I test firmware for the Rc car without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
