Questions
How big is the Sense slim PCB?
It measures 44 × 42.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sense slim use?
75 parts, built around the BME280, LIS3MDL, MBR0530 and IRLML0030TR-VB. 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 Sense slim KiCad files?
From the bartoszp1992/tacho3 repository on GitHub, at the commit this page was made from: the board is pcb/sense_slim/sense_slim.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sense slim design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
