Keyboard: common questions

What microcontroller does the Keyboard use?

The Keyboard is built around the RP2350_STAMP, from the RP2040/RP2350 family.

How big is the Keyboard PCB?

The Keyboard measures 387.8 × 163.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Keyboard?

343 components, from 17 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 Keyboard design files?

From the ayushj-18/keyboard 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 Keyboard design in my own project?

The repository has no license, so all rights stay with ayushj-18. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Keyboard 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.
