Questions
How big is the ARMband PCB?
It measures 48.8 × 40.2 mm and has 6 copper layers, 1.6 mm thick.
What parts does the ARMband use?
104 parts, built around the NRF52832-CIAA-G-R7, BMM350, MAX30102 and TLE493DW2B6A0HTSA1. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ARMband KiCad files?
From the SetZero/ARMband repository on GitHub, at the commit this page was made from: the board is armband.kicad_pcb and its schematic 6dof.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ARMband design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
