README.mdpi.runner
pi.runner is a BLE IoT device, that turns my noemal 'dumb' treadmill into a smart treadmil that connects to google health and reads the distance covered and my pase accurately
This device directly integrates into my old treadmil through handwitring, it will draw power forom the treadmil console's 2x AA batteris, which voltage is steppded up via voltage booster, also the inbuild reed switch magnetic sensor of the tradmill will be hoked directly to my custom made pcb.

Questions
How big is the Pi.runner PCB?
It measures 25.4 × 31.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pi.runner use?
5 parts, built around the SK6812MINI-E. 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 Pi.runner KiCad files?
From the piVerified/pi.runner repository on GitHub, at the commit this page was made from: the board is PCB/pi.runner.kicad_pcb and its schematic PCB/pi.runner.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pi.runner 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).
