Questions
How big is the PCBA KB25 PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PCBA KB25 use?
113 parts, built around the ESP32-S3FN8, RP2040, W25Q64JVSSIQ and 74HC4051. 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 KB25 KiCad files?
From the intechstudio/grid-hardware repository on GitHub, at the commit this page was made from: the board is Electrical/Design/PCBA-KB25/PCBA-KB25.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCBA KB25 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).
