Questions
How big is the Tcvr PCB?
It measures 56.1 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tcvr use?
48 parts, built around the LM386, BC817 and PZT2222A. 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 Tcvr KiCad files?
From the danielcsirke/morse-tcvr repository on GitHub, at the commit this page was made from: the board is tcvr.kicad_pcb and its schematic tcvr.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tcvr design in my own project?
Its repository states no licence, so its author keeps all rights: ask danielcsirke before reusing the design.
