Questions
How big is the Gem PCB?
It measures 56 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Gem use?
40 parts, built around the AD8226BRZ, AD8538ARZ, ADS1115 and TCR2EF. 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 Gem KiCad files?
From the ajakef/gem-hardware repository on GitHub, at the commit this page was made from: the board is Gem.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gem 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).
