Questions
How big is the TEP000 PCB?
It measures 45 × 45 mm and has 4 copper layers, 1.6 mm thick.
What parts does the TEP000 use?
54 parts, built around the ATXMEGA8E5-AN, TEMD5510FX01 and 2N7002 K72. 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 TEP000 KiCad files?
From the davidholmes1066/HR_Monitor repository on GitHub, at the commit this page was made from: the board is TEP000/TEP000.kicad_pcb and its schematic TEP000/Analog.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TEP000 design in my own project?
Its repository states no licence, so its author keeps all rights: ask davidholmes1066 before reusing the design.
