Questions
How big is the Hotswap tb PCB?
It measures 36.1 × 25.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hotswap tb use?
23 parts, built around the TPS2493PW and BUK7208-40B. 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 Hotswap tb KiCad files?
From the dodotronix/breakout_pcbs repository on GitHub, at the commit this page was made from: the board is hotswap_tb/hotswap_tb.kicad_pcb and its schematic hotswap_tb/hotswap_tb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hotswap tb design in my own project?
Its repository states no licence, so its author keeps all rights: ask dodotronix before reusing the design.
