Questions
How big is the Toe Walker Tiny Stack Design V3 PCB?
It measures 39.4 × 40.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Toe Walker Tiny Stack Design V3 use?
17 parts, built around the ADS1115IDGS and BMA250. 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 Toe Walker Tiny Stack Design V3 KiCad files?
From the Biggs406/Toe_Walker_Specs repository on GitHub, at the commit this page was made from: the board is KiCad Files/Toe_Walker_Tiny_Stack_Design_V3.kicad_pcb and its schematic KiCad Files/Toe_Walker_Tiny_Stack_Design_V3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Toe Walker Tiny Stack Design V3 design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
