Questions
How big is the First PCB?
It measures 99.5 × 99.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the First use?
14 parts, built around the WEMOS D1 MINI. 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 First KiCad files?
From the shreegw/PCB-Design repository on GitHub, at the commit this page was made from: the board is 2. Wemos Mask/WeMos/First.kicad_pcb and its schematic 1.Single_Channel_Relay/1_Channel_Relay_Files/1_Channel_Relay.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the First 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).
