Kaya: common questions

What microcontroller does the Kaya use?

The Kaya is built around the XIAO-NRF52840-SMD, from the Nordic nRF family.

How big is the Kaya PCB?

The Kaya measures 197.9 × 149.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Kaya?

82 components, from 13 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 Kaya design files?

From the karnxx/kayboard 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 Kaya design in my own project?

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

Can I test firmware for the Kaya 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.
