## What it is
An open-source hardware and firmware project for a tiny PCB-based RC car built around the ESP32-H2, including KiCad schematics, gerbers, 3D-printable mechanical parts, and Python scripts. It bundles motor-control firmware, a keyboard driving controller, and neural network training scripts for autonomous color-based line following.

## Use cases
- build your own tiny open-source RC car
- flash custom firmware onto an ESP32-H2 motor controller
- train a neural network to drive a line-following robot
- drive a robot car from a keyboard over serial
- learn PCB design with complete KiCad files and gerbers
- 3D print an enclosure and wheels for a micro robot
- hack a ChatGPT/LLM-driven physical robot

## When to choose
- you want a complete open-source hardware + firmware + software robot car project
- you are learning embedded development on ESP32 with real hardware
- you want to experiment with ML-based line following on a physical robot
- you need reference KiCad designs for a small motor-control PCB

## When to avoid
- you need a production-ready or polished consumer RC car
- you want a simulator-only project without buying or fabricating hardware
- you need a supported product with warranty or documentation-grade code quality
- you require platforms other than ESP32-H2
