Questions
How big is the Node.IO E1 PCB?
It measures 50 × 40 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Node.IO E1 use?
50 parts, built around the BME688, CP2102N-A02-GQFN28R, MEM2085-00-115-00-A and BMI323. 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 Node.IO E1 KiCad files?
From the dsimat/Node.IO-E1 repository on GitHub, at the commit this page was made from: the board is Node.IO E1.kicad_pcb and its schematic Node.IO E1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Node.IO E1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask dsimat before reusing the design.
