Questions
How big is the Tansa PCB?
It measures 76 × 90 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Tansa use?
51 parts, built around the TEENSY 4.1 and L7805. 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 Tansa KiCad files?
From the Tedros00/tansa repository on GitHub, at the commit this page was made from: the board is mobo/Tansa/Tansa.kicad_pcb and its schematic mobo/Tansa/Tansa.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tansa design in my own project?
Its repository states no licence, so its author keeps all rights: ask Tedros00 before reusing the design.
