ChrisKeyboards: common questions

What microcontroller does the ChrisKeyboards use?

The ChrisKeyboards is built around the ESP32-S3-DevKitC, from the ESP32 family.

How big is the ChrisKeyboards PCB?

The ChrisKeyboards measures 49.6 × 26.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ChrisKeyboards?

8 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the ChrisKeyboards design files?

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

Can I use the ChrisKeyboards design in my own project?

Yes, under the terms of its GPL-3.0 license, which MagicTINTIN chose for the repository.

Can I test firmware for the ChrisKeyboards 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.
