Its main chip is the ESP32-S3-WROOM-1-N8R8, from the ESP32 family. Other key parts include the TLV75901PDRVR. By type, the board carries 9 resistors, 5 capacitors, 2 ICs and 2 switches.

It belongs with the power & battery, sensors and displays & leds designs in this gallery.

From the project

KiCAD EDA automatic component placement tool

A hackable, battery‑powered LED badge built with Atopile for hardware and PlatformIO/Arduino for firmware. It features a 10×10 SK6805 LED matrix, an ESP32‑C3 module, USB‑C power/data, on‑board charging and regulation, a 6‑axis IMU, an I²S microphone, and a user button. Press the button to cycle through multiple visual/audio‑reactive modes.

Esp32 minimal: common questions

What microcontroller does the Esp32 minimal use?

The Esp32 minimal is built around the ESP32-S3-WROOM-1-N8R8, from the ESP32 family.

How big is the Esp32 minimal PCB?

The Esp32 minimal measures 34.2 × 26.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32 minimal?

19 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32 minimal design files?

From the glovepost/atoplace repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Esp32 minimal design in my own project?

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

Can I test firmware for the Esp32 minimal 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.
