ArrythmiX: common questions

What microcontroller does the ArrythmiX use?

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

How big is the ArrythmiX PCB?

The ArrythmiX measures 39.5 × 28.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ArrythmiX?

37 components, from 23 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 ArrythmiX design files?

From the TTF-fog/ArrythmiX 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 ArrythmiX design in my own project?

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

Can I test firmware for the ArrythmiX 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.
