The KiCad project lives in the howardt12345/keyboard0 repository on GitHub; these links point at the commit this page was built from.

Custom keyboard (f303, fe2.1): common questions

What microcontroller does the Custom keyboard (f303, fe2.1) use?

The Custom keyboard (f303, fe2.1) is built around the MIC2505-1YM, from the STM32 family.

How big is the Custom keyboard (f303, fe2.1) PCB?

The Custom keyboard (f303, fe2.1) measures 395.3 × 138.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Custom keyboard (f303, fe2.1)?

413 components, from 148 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 Custom keyboard (f303, fe2.1) design files?

From the howardt12345/keyboard0 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Custom keyboard (f303, fe2.1) design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Custom keyboard (f303, fe2.1) without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
