Board: common questions

What microcontroller does the Board use?

The Board is built around the Seeeduino XIAO BLE, from the Nordic nRF family.

How big is the Board?

The Board measures 111.7 × 92.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Board?

40 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the Board design files?

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

Can I use the Board design in my own project?

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

Can I test firmware for the Board 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.
