Questions
How big is the Conv3 PCB?
It measures 19 × 34 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Conv3 use?
6 parts. 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 Conv3 KiCad files?
From the 74th/74th-oshw-projects repository on GitHub, at the commit this page was made from: the board is 74TH-G028-conv3_grove_qwiic_xh2.5_transfer_board/conv3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Conv3 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).
