Pixel Dust: common questions

What microcontroller does the Pixel Dust use?

The Pixel Dust is built around the ESP32-C3_SUPERMINI_TH, from the ESP32 family.

How big is the Pixel Dust PCB?

The Pixel Dust measures 136.9 × 148.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pixel Dust?

402 components, from 11 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 Pixel Dust design files?

From the hackclub/pixeldust 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 Pixel Dust design in my own project?

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

Can I test firmware for the Pixel Dust 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.
