Ledboard: common questions

What microcontroller does the Ledboard use?

The Ledboard is built around the XIAO-ESP32-S3-DIP, from the ESP32 family.

How big is the Ledboard PCB?

The Ledboard measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ledboard?

235 components, from 6 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 Ledboard 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 Ledboard 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 Ledboard 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.
