KeyboardProject: common questions

What microcontroller does the KeyboardProject use?

The KeyboardProject is built around the Teensy4.0, from the NXP family.

How big is the KeyboardProject PCB?

The KeyboardProject measures 311.9 × 123.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the KeyboardProject?

157 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the KeyboardProject design files?

From the Henripru/KeyboardProject repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the KeyboardProject design in my own project?

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

Can I test firmware for the KeyboardProject without the hardware?

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