Questions
How big is the Iolggr PCB?
It measures 27.9 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Iolggr use?
21 parts, built around the BMP280 and LD1117S33CTR-HXY. 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 Iolggr KiCad files?
From the xlfe/iolggr repository on GitHub, at the commit this page was made from: the board is hardware/kicad_files/board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Iolggr design in my own project?
Its repository states no licence, so its author keeps all rights: ask xlfe before reusing the design.
