Dya panelized: common questions

What microcontroller does the Dya panelized use?

The Dya panelized is built around the XIAO-nRF52840-SMD, from the Nordic nRF family.

How big is the Dya panelized PCB?

The Dya panelized measures 187.9 × 127.2 mm, has 2 copper layers and is 1.29 mm thick.

How many components are on the Dya panelized?

256 components, from 45 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dya panelized design files?

From the cormoran/dya-dash-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 panelized 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 panelized without the hardware?

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