Evrerything is bought from aliexpress, see links. Prices as of writing. # OBS! Full case file The complete case-file was to big for github, therefor i uploaded it to the slack cdn: https://hc-cdn.hel1.your-objectstorage.com/s/v3/3df98c002cca8f447206d590c6b9a0739d3f8359akeyboardv1

A keyboard: common questions

What microcontroller does the A keyboard use?

The A keyboard is built around the Raspberry_Pi_Pico_THT, from the Raspberry Pi family.

How big is the A keyboard PCB?

The A keyboard measures 313.5 × 124.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the A keyboard?

163 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the A keyboard design files?

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

Can I use the A keyboard design in my own project?

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

Can I test firmware for the A keyboard without the hardware?

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