Questions
How big is the HV PCB redesign PCB?
It measures 129.4 × 135.1 mm and has 2 copper layers, 1.81 mm thick.
What parts does the HV PCB redesign use?
18 parts, built around the DBR71205-HR, KT12-1A-40L-THT and TSC-112L3H,000. 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 HV PCB redesign KiCad files?
From the Bulldogs-Racing/HV-PCB repository on GitHub, at the commit this page was made from: the board is HV PCB redesign.kicad_pcb and its schematic HV PCB redesign.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HV PCB redesign design in my own project?
Its repository states no licence, so its author keeps all rights: ask Bulldogs-Racing before reusing the design.
