This project is a remote controlled Hotwheels. Here you can find the Ki-cad design files and STM32 project
This repository contains all the files and documentation for our DIY remote-controlled Hot Wheels car. We designed our own custom PCB using KiCad, featuring a NRF24L01 transceiver(We only used it as a receiver for now) for wireless communication, an H-bridge BD6211F-E2 to control a DC motor for propulsion, a 600mAh LiPo battery for power, and a linear servo motor for precise steering control.

Questions
How big is the RC Hotwheels PCB?
It measures 29.5 × 21.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RC Hotwheels use?
16 parts, built around the STM32F070F6P6, BD6211F-E2, MIC5504-3.3YM5-TR and OS102011MS2QN1. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the RC Hotwheels KiCad files?
From the 404boboo/RC-Hotwheels repository on GitHub, at the commit this page was made from: the board is KiCad-Files/rc_hotwheels.kicad_pcb and its schematic KiCad-Files/rc_hotwheels.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RC Hotwheels design in my own project?
Its repository states no licence, so its author keeps all rights: ask 404boboo before reusing the design.
