Questions
How big is the Echo pcb PCB?
It measures 80 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Echo pcb use?
20 parts, built around the BSS138. 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 Echo pcb KiCad files?
From the OpenIotNetwork/echo-pcb repository on GitHub, at the commit this page was made from: the board is pcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Echo pcb design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
