Ws2812-matrix: common questions

What microcontroller does the Ws2812-matrix use?

The Ws2812-matrix is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Ws2812-matrix PCB?

The Ws2812-matrix measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Ws2812-matrix?

290 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the Ws2812-matrix design files?

From the MTalon63/PCBs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Ws2812-matrix design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Ws2812-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.
