About the GlowPad PCB

GlowPad is an open source ESP32 PCB design by StuckAtPrototype, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 108 × 70 mm, with 40 components from 19 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the AP2205. By type, the board carries 10 capacitors, 10 resistors, 7 switches, 5 LEDs, 3 diodes and 2 ICs.

From the project

A multi-mode interactive pad built on the ESP32-S3 with 5 capacitive touch keys, 5 WS2812B LEDs, and a piezo buzzer. Supports five modes: a Pomodoro timer, a pentatonic piano, a Simon-style memory game, a reaction speed game, and a USB media-control (keyboard) mode for music play

GlowPad: common questions

What microcontroller does the GlowPad use?

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

How big is the GlowPad PCB?

The GlowPad measures 108 × 70 mm, has 2 copper layers and is 1.66 mm thick.

How many components are on the GlowPad?

40 components, from 19 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 GlowPad design files?

From the StuckAtPrototype/GlowPad 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 GlowPad design in my own project?

Yes, under the terms of its Apache-2.0 license, which StuckAtPrototype chose for the repository.

Can I test firmware for the GlowPad 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.
