Pixel: common questions

What microcontroller does the Pixel use?

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

How big is the Pixel PCB?

The Pixel measures 95 × 85.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pixel?

80 components, from 22 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 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 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 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.
