Questions
How big is the ContactorDriver PCB?
It measures 66 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ContactorDriver use?
37 parts, built around the RI3-1212S, INA2132U, CSD18511KTT and V2F22HM3/H. 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 ContactorDriver KiCad files?
From the lhr-solar/Contactor-DriverPCB repository on GitHub, at the commit this page was made from: the board is ContactorDriver.kicad_pcb and its schematic ContactorDriver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ContactorDriver design in my own project?
Its repository states no licence, so its author keeps all rights: ask lhr-solar before reusing the design.
