About the ESP32-Breadboard-Devboard PCB

ESP32-Breadboard-Devboard is an open source ESP32 PCB design by mgollapudi104, published on GitHub. It is a 2-layer board measuring 21 × 73 mm, with 25 components from 16 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the USBLC6-2SC6 and AMS1117-3.3. By type, the board carries 9 capacitors, 5 resistors, 3 ICs, 2 connectors, 2 switches and 2 diodes.

It belongs with the dev boards & breakouts and iot & wireless designs in this gallery.

From the project

This project is an ESP32-S3-WROOM-1 devboard that can fit on a breadboard, unlike standard ESP32 DevKit V1s. I made it because my current ESP32s don't fit on a breadboard and it makes it really difficult to prototype easily, so this fixes that problem.

ESP32-Breadboard-Devboard: common questions

What microcontroller does the ESP32-Breadboard-Devboard use?

The ESP32-Breadboard-Devboard is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the ESP32-Breadboard-Devboard PCB?

The ESP32-Breadboard-Devboard measures 21 × 73 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-Breadboard-Devboard?

25 components, from 16 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-Breadboard-Devboard design files?

From the mgollapudi104/ESP32-Breadboard-Devboard 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-Breadboard-Devboard design in my own project?

The repository has no license, so all rights stay with mgollapudi104. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ESP32-Breadboard-Devboard 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.
