Questions
How big is the Main Brd PCB?
It measures 99.1 × 85.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Main Brd use?
64 parts, built around the ARJM11C7-114-BA-EW2, ATWINC1500-MR210PB1952-T, ENC28J60-I/SP and SX1272IMLTRT. 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 Main Brd KiCad files?
From the bluebandit21/magic-wifi repository on GitHub, at the commit this page was made from: the board is PCB/KiCAD/Main_Brd/Main_Brd.kicad_pcb and its schematic PCB/KiCAD/Main_Brd/Main_Brd.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Main Brd 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).
