About the Esp32build PCB

Esp32build is an open source ESP32 PCB design by ihmnelson, published on GitHub. It is a 4-layer board measuring 100 × 100 mm, with 57 components from 31 distinct parts.

Its main chip is the ESP32-S3-WROOM-2, from the ESP32 family. Other key parts include the TPS62A02NDRL, USBLC6-2SC6, MCP23017x-x-ML and MAX98357A. By type, the board carries 20 resistors, 12 switches, 11 capacitors, 5 ICs, 4 connectors and 3 diodes.

It belongs with the audio, power & battery and retro computing designs in this gallery.

From the project

Handheld game/macropad device, roughly halfway between a Stream Deck and a Game Boy. Personal learning project — KiCad hardware design, not yet fabbed.

Handheld game/macropad device, roughly halfway between a Stream Deck and a Game Boy. Personal learning project — KiCad hardware design, not yet fabbed.

Schematic-in-progress. Root sheet is wired, ERC is mostly clean, footprints are not yet fully assigned. Not ready for PCB layout. See esp32-board-design.md for the full design log — decisions, part numbers, GPIO budget, and open items, all dated and kept current. That file is the source of truth; this README is just an orientation.

Esp32build: common questions

What microcontroller does the Esp32build use?

The Esp32build is built around the ESP32-S3-WROOM-2, from the ESP32 family.

How big is the Esp32build PCB?

The Esp32build measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Esp32build?

57 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32build design files?

From the ihmnelson/ESP32-Embedded-Console repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Esp32build design in my own project?

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

Can I test firmware for the Esp32build 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.
