Questions
How big is the EMonTx PCB?
It measures 100 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EMonTx use?
50 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 EMonTx KiCad files?
From the mbinmdfa/Cognisense repository on GitHub, at the commit this page was made from: the board is eMonTx.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EMonTx design in my own project?
Its repository states no licence, so its author keeps all rights: ask mbinmdfa before reusing the design.
