Questions
How big is the Tt ecp5-cb PCB?
It measures 50 × 52 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Tt ecp5-cb use?
32 parts, built around the TLV73325PDBV and KT-0603R. 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 Tt ecp5-cb KiCad files?
From the MichaelBell/tt-ecp5-bb repository on GitHub, at the commit this page was made from: the board is tt-ecp5-cb.kicad_pcb and its schematic tt-ecp5-cb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tt ecp5-cb design in my own project?
Its repository states no licence, so its author keeps all rights: ask MichaelBell before reusing the design.
