About the ESP 32 Battle PCB

ESP 32 Battle is an open source ESP32 PCB design by samcwitte, published on GitHub under the MIT license. It is a 4-layer board measuring 64.4 × 103.2 mm, with 68 components from 27 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the USBLC6-2SC6, AP2112K-3.3, MCP73831-2-OT, BME280 and AS1115-BSST. By type, the board carries 26 resistors, 23 ICs, 8 capacitors, 6 connectors, 2 switches and 2 diodes.

It belongs with the sensors and iot & wireless designs in this gallery.

From the project

This is a repository containing my PCB designs for a 2-hour PCB battle I participated in with Predictable Designs on YouTube.

The video hasn't been released yet, but I'll update this line when it is.[]()

This design battle was to take place over the course of 2 hours, during which the participants and I would have to complete the schematic capture and PCB layout. Here's the design guidelines we were given:

ESP 32 Battle: common questions

What microcontroller does the ESP 32 Battle use?

The ESP 32 Battle is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the ESP 32 Battle PCB?

The ESP 32 Battle measures 64.4 × 103.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESP 32 Battle?

68 components, from 27 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 ESP 32 Battle design files?

From the samcwitte/PCB-Design-Battle 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 ESP 32 Battle design in my own project?

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

Can I test firmware for the ESP 32 Battle 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.
