From the project

YUIOP: Etude of designing keyboards

YUIOP keyboards are experimental original keyboards designed by KoRoN.

* yuiop27/ - separate keyboard prototype.

* yuiop54/main - signle board keyboard prototype.

combined right and left-hand boards of yuiop27. PCB dimension is 285.00mm x 94.60mm (GH60 compatible form factor without screw holes).

* yuiop54/main2 - researching version of yuiop54.

multi-sheets schematic. fix layout for auto routing. introduce GND cupper fill. * rev.B - trial to make compatible with GH60 (include screw holes).

YUIOP29RE: common questions

What microcontroller does the YUIOP29RE use?

The YUIOP29RE is built around the RP2040_breakout, from the RP2040/RP2350 family.

How big is the YUIOP29RE PCB?

The YUIOP29RE measures 116.5 × 116.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the YUIOP29RE?

118 components, from 21 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 YUIOP29RE design files?

From the koron/yuiop 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 YUIOP29RE design in my own project?

Yes, under the terms of its MIT license, which koron chose for the repository.

Can I test firmware for the YUIOP29RE 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.
