Questions
How big is the Bridge PCB?
It measures 95 × 72 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bridge use?
31 parts, built around the TLP250(F) and L7805. 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 Bridge KiCad files?
From the 53175ddd/3P-VVVF repository on GitHub, at the commit this page was made from: the board is Bridge/Bridge.kicad_pcb and its schematic Bridge/Bridge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bridge design in my own project?
Its repository states no licence, so its author keeps all rights: ask 53175ddd before reusing the design.
