Questions
How big is the Tl40 pcb PCB?
It measures 298.3 × 88.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tl40 pcb use?
125 parts, built around the ATMEGA32U4-MU. 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 Tl40 pcb KiCad files?
From the Iipal/teethless40 repository on GitHub, at the commit this page was made from: the board is PCB/tl40_pcb.kicad_pcb and its schematic Cases/FR4/plate_gerbers/plate_gerbers.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tl40 pcb design in my own project?
Its repository publishes it under the WTFPL licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
