Capstone
torrefic/15A-Motor-Driver2This H-Bridge PCB uses the Allegro "A4957: Full Bridge MOSFET Driver" as a gate driver for 4 N-MOSFETs. The board is rated for 15A without heatsinks on the MOSFETs, but can sink larger currents depending on the size of the heatsinks. This board was developped using KiCad software and was ordered on https://jlcpcb.com/m

Questions
How big is the Capstone PCB?
It measures 98 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Capstone use?
37 parts, built around the DMTH6002LPS. 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 Capstone KiCad files?
From the torrefic/15A-Motor-Driver repository on GitHub, at the commit this page was made from: the board is Final Version - Capstone - Motor Driver Large Motor/Capstone.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Capstone design in my own project?
Its repository states no licence, so its author keeps all rights: ask torrefic before reusing the design.
