Keyboard(0): common questions

What microcontroller does the Keyboard(0) use?

The Keyboard(0) is built around the Raspberry_Pi_Pico, from the RP2040/RP2350 family.

How big is the Keyboard(0) PCB?

The Keyboard(0) measures 357.2 × 117.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Keyboard(0)?

175 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the Keyboard(0) design files?

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

Can I use the Keyboard(0) design in my own project?

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

Can I test firmware for the Keyboard(0) without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
