Questions
How big is the Bled pico w backpack PCB?
It measures 23.4 × 51.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bled pico w backpack use?
40 parts, built around the TF-15X15. 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 Bled pico w backpack KiCad files?
From the DanNixon/bled repository on GitHub, at the commit this page was made from: the board is pcb/bled-pico-w-backpack/bled-pico-w-backpack.kicad_pcb and its schematic pcb/bled-pico-w-backpack/bled-pico-w-backpack.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bled pico w backpack 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).
