About the ESP32-modules PCB

ESP32-modules is an open source ESP32 PCB design by digitalforger73, published on GitHub under the Custom license license. It is a 4-layer board measuring 80.5 × 28.2 mm, with 37 components from 18 distinct parts.

Its main chip is the ESP32-WROOM-32E, from the ESP32 family. Other key parts include the AMS1117-3.3 and CH340C. By type, the board carries 11 capacitors, 11 resistors, 3 ICs, 3 connectors, 3 diodes and 2 transistors.

It belongs with the sensors, iot & wireless and usb & debug tools designs in this gallery.

From the project

Kicad projects based on ESP32

An open community project for learning ESP32 hardware design with KiCad.

This repository contains a complete ESP32 development board designed in KiCad, intended for makers, students, and engineers who want to learn custom PCB design and build their own ESP32-based hardware.

Need an ESP32 board with integrated sensors?

The ESP32 Sensor Board extends the Community Edition with a complete environmental sensing platform, making it suitable for IoT development, plant monitoring, and custom hardware projects.

ESP32-modules: common questions

What microcontroller does the ESP32-modules use?

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

How big is the ESP32-modules PCB?

The ESP32-modules measures 80.5 × 28.2 mm, has 4 copper layers and is 1.564 mm thick.

How many components are on the ESP32-modules?

37 components, from 18 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 ESP32-modules design files?

From the digitalforger73/ESP32-modules-kicad 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 ESP32-modules design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the ESP32-modules 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.
