4WD ESP32 Bluetooh Robo Race bot

A fully customizable 4-wheel drive robot controlled via bluetooh using an ESP-32 and L298N motor driver.

Overview

This project is a 4WD robot built aroubd the ESP32 microcontroller. It uses an L298N motor driver to control four TT/BO gear motors, powered by a 3S 18650 li-ion battery pack. The robot can be controlled wirelessly via bluetooh using any phone or computer with a serial terminal app.

The project was designed from the ground up. All design files, firmware and documentation are included in this repo to make it fully reproducible.

  • Why I build this:

I wanted to learn hardware design form scratch. This project forced me to understand every component in detail.

Questions

How big is the L298 Module PCB?

It measures 53.3 × 45.7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the L298 Module use?

22 parts, built around the L298HN and L7805. 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 L298 Module KiCad files?

From the VritoX098/ROBO-RACE-BOT repository on GitHub, at the commit this page was made from: the board is PCB/L298 Module.kicad_pcb and its schematic PCB/L298 Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the L298 Module design in my own project?

Its repository states no licence, so its author keeps all rights: ask VritoX098 before reusing the design.
