5x5x Led Matrix by hand

A DIY 5x5 LED matrix made with 25 LEDs, an ESP32 and a zero PCB.

The matrix can display numbers 1–6 and works as a simple digital dice. Pressing the button generates a random number and shows a short rolling animation before displaying the result.

- ESP32 - 25 LEDs - 5 × 330Ω resistors - Push button - Zero PCB

- R1 → GPIO 22 - R2 → GPIO 19 - R3 → GPIO 23 - R4 → GPIO 18 - R5 → GPIO 5

5x5-LED-matrix: common questions

What microcontroller does the 5x5-LED-matrix use?

The 5x5-LED-matrix is built around the ESP32_30pin, from the ESP32 family.

How big is the 5x5-LED-matrix PCB?

The 5x5-LED-matrix measures 73 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 5x5-LED-matrix?

32 components, from 4 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 5x5-LED-matrix design files?

From the chonki29/5x5-LED-matrix 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 5x5-LED-matrix design in my own project?

The repository has no license, so all rights stay with chonki29. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 5x5-LED-matrix 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.
