Questions
How big is the Transmanium PCB?
It measures 69.8 × 75.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Transmanium use?
29 parts, built around the BF245A. 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 Transmanium KiCad files?
From the Acramonics/transmanium repository on GitHub, at the commit this page was made from: the board is kicad/transmanium.kicad_pcb and its schematic kicad/transmanium.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Transmanium design in my own project?
Its repository states no licence, so its author keeps all rights: ask Acramonics before reusing the design.
