From the project

Custom-built controller for an RC car project, designed from scratch to explore embedded hardware and firmware.

Custom-built controller for an RC car project, designed from scratch to explore embedded hardware and firmware.

This project started as a way to: - learn more about hardware design - build firmware using Zephyr RTOS - understand a full embedded system from end to end

The long-term goal is to build both: - 🚗 the car - 🎮 the controller

This repository focuses on the controller pad.

Hw rc car pad: common questions

What microcontroller does the Hw rc car pad use?

The Hw rc car pad is built around the C3029185, from the STM32 family.

How big is the Hw rc car pad PCB?

The Hw rc car pad measures 149.5 × 66 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Hw rc car pad?

71 components, from 21 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 Hw rc car pad design files?

From the bszyca/hw_rc_car_pad 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 Hw rc car pad design in my own project?

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

Can I test firmware for the Hw rc car pad without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
