About the PixelBoard PCB

PixelBoard is an open source ESP32 PCB design by hamzaa-exe, published on GitHub under the MIT license. It is a 2-layer board measuring 33 × 45 mm, with 21 components from 15 distinct parts.

Its main chip is the ESP32-WROOM-32, from the ESP32 family. Other key parts include the 74AHCT125, AP2112K-3.3 and CH340C. By type, the board carries 7 capacitors, 5 resistors, 4 ICs, 2 connectors, 2 switches and 1 fuse.

It belongs with the displays & leds designs in this gallery.

From the project

LED display using Sparkle Motion and a 16x16 NeoPixel matrix. Use WLED software to play awesome animations that are designed for 2D matrices. A 3D printed frame and piece of black LED acrylic create an assembled display that can sit upright or mounted to a wall.

PixelBoard: common questions

What microcontroller does the PixelBoard use?

The PixelBoard is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the PixelBoard PCB?

The PixelBoard measures 33 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PixelBoard?

21 components, from 15 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 PixelBoard design files?

From the hamzaa-exe/PixelBoard 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 PixelBoard design in my own project?

Yes, under the terms of its MIT license, which hamzaa-exe chose for the repository.

Can I test firmware for the PixelBoard 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.
