Questions
How big is the LedCollar PCB PCB?
It measures 30 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LedCollar PCB use?
43 parts, built around the AP2112K-3.3, MPU-6050 and AO3400A. 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 LedCollar PCB KiCad files?
From the LeoDJ/ledCollar repository on GitHub, at the commit this page was made from: the board is ledCollar_PCB/ledCollar_PCB.kicad_pcb and its schematic ledCollar_PCB/ledCollar_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LedCollar PCB 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).
