Questions
How big is the Triple Half Bridge Driver v4a PCB?
It measures 221.5 × 150.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Triple Half Bridge Driver v4a use?
342 parts, built around the INA240A1D, IRS2101PBF, IRF740 and IRF9540NS. 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 Triple Half Bridge Driver v4a KiCad files?
From the rhysyim/Electronic-Speed-Controller repository on GitHub, at the commit this page was made from: the board is PCB/Triple Half Bridge Driver v4a/PCB/PCB.kicad_pcb and its schematic PCB/Triple Half Bridge Driver v2/PCB/PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Triple Half Bridge Driver v4a design in my own project?
Its repository states no licence, so its author keeps all rights: ask rhysyim before reusing the design.
