Questions
How big is the PCBA BU16 PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PCBA BU16 use?
292 parts, built around the RP2350A, HAL49ESO, LMV321 and GD25B64ESIGR. 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 PCBA BU16 KiCad files?
From the intechstudio/grid-hardware repository on GitHub, at the commit this page was made from: the board is Electrical/Design/PCBA-BU16/PCBA-BU16.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCBA BU16 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
