Questions
How big is the TinyTendo PCB?
It measures 64.7 × 52.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the TinyTendo use?
51 parts, built around the 74HC139D and 74HC373D. 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 TinyTendo KiCad files?
From the Redherring32/TinyTendo repository on GitHub, at the commit this page was made from: the board is Hardware/Motherboard/TinyTendo.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TinyTendo design in my own project?
Its repository states no licence, so its author keeps all rights: ask Redherring32 before reusing the design.
