Questions
How big is the TSAL PCB?
It measures 28 × 21.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TSAL use?
12 parts, built around the SMF4L26A, 150353GS74500 and 150353RS74500. 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 TSAL KiCad files?
From the B3N64/TSAL repository on GitHub, at the commit this page was made from: the board is TSAL.kicad_pcb and its schematic TSAL.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TSAL design in my own project?
Its repository states no licence, so its author keeps all rights: ask B3N64 before reusing the design.
