Questions
What parts does the LowPowerLEDSmartWatch use?
12 parts, built around the BM832 and LTP-305G. 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 LowPowerLEDSmartWatch KiCad files?
From the StevenKnudsen/LowPowerLEDSmartWatch repository on GitHub, at the commit this page was made from: the board is hardware/hardware.kicad_pcb and its schematic hardware/BLE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LowPowerLEDSmartWatch 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).
