Dya left: common questions

What microcontroller does the Dya left use?

The Dya left is built around the RP2040-Zero, from the RP2040/RP2350 family.

How big is the Dya left PCB?

The Dya left measures 141.9 × 113.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dya left?

90 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dya left design files?

From the cormoran/dya-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 Dya left design in my own project?

Yes, under the terms of its CC-BY-4.0 license, which cormoran chose for the repository.

Can I test firmware for the Dya left 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.
