About the ESP32-S2-Breakout

ESP32-S2-Breakout is an open source ESP32 PCB design by eggsampler, published on GitHub under the MIT license. It is a 2-layer board measuring 61 × 30.5 mm, with 37 components from 24 distinct parts.

Its main chip is the ESP32-S2-WROVER, from the ESP32 family. Other key parts include the USBLC6-2SC6 and XC6220B331MR. By type, the board carries 11 capacitors, 11 resistors, 3 ICs, 3 connectors, 2 switches and 2 diodes.

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

From the project

A minimal breakout board for the new ESP32-S2-WROOM module

May 2021: New v2 boards assembled with USB-C connector, tested and working well over USB CDC-ACM and DFU programming.

Feb 2021: Updated to v2, switched from micro usb to usb-c connector, minor routing changes. PCB ordered, updates to come.

July 2020: Board has been assembled, but not fully tested. Currently waiting for ESP-IDF release with full s2 support.

This board is a minimal breakout board for the new ESP32-S2-WROOM module from Espressif. It was designed with a few criteria in mind,

ESP32-S2-Breakout: common questions

What microcontroller does the ESP32-S2-Breakout use?

The ESP32-S2-Breakout is built around the ESP32-S2-WROVER, from the ESP32 family.

How big is the ESP32-S2-Breakout?

The ESP32-S2-Breakout measures 61 × 30.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-S2-Breakout?

37 components, from 24 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-S2-Breakout design files?

From the eggsampler/ESP32-S2-Breakout repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the ESP32-S2-Breakout design in my own project?

Yes, under the terms of its MIT license, which eggsampler chose for the repository.

Can I test firmware for the ESP32-S2-Breakout 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.
