About the Linefollower PCB

Linefollower is an open source ESP32 PCB design by Krzysiek-Mistrz, published on GitHub. It is a 2-layer board measuring 47.5 × 51 mm, with 19 components from 14 distinct parts.

Its main chip is the ESP32-WROOM-32, from the ESP32 family. Other key parts include the TB6612FNG, CP2102N-Axx-xQFN28 and LM2596S-3.3. By type, the board carries 4 ICs, 4 capacitors, 2 modules, 2 switches, 1 battery holder and 1 resistor.

It belongs with the robotics & motion designs in this gallery.

From the project

elektronika

Welcome to my electronics repository! This is the place where I store all my ppcbs, models and code for some of my projects1.

This repository serves as a central hub for all the mechanical side of my robotic and automatic projects. It includes pcbs, models, and codes. Here, you will find a diverse collection of my works.

The repository is organized by ECAD programs in which I have designed my PCBS and project type. In these folders you will find each project associated with this program. There's also models folder in which I have prepared all my models for my projects in CAD programs like…

Linefollower: common questions

What microcontroller does the Linefollower use?

The Linefollower is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Linefollower PCB?

The Linefollower measures 47.5 × 51 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Linefollower?

19 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the Linefollower design files?

From the Krzysiek-Mistrz/electronics_robotics_designs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Linefollower design in my own project?

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

Can I test firmware for the Linefollower 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.
