Questions
How big is the Mecha Dev Expander PCB?
It measures 65 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mecha Dev Expander use?
30 parts, built around the TCA9554DW and 24LC256-I/P. 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 Mecha Dev Expander KiCad files?
From the SolidwareGit/Modular-GP2040-Dev-Board repository on GitHub, at the commit this page was made from: the board is Mecha Dev Expander/Mecha Dev Expander.kicad_pcb and its schematic Mecha Dev Board/Mecha Dev Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mecha Dev Expander 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).
