efebasol/StepperMotorController
Rev A — single-motor bench prototype power board. Feeds the driver board (48 V), the stepper motor brake (24 V) and the logic (5 V / 3V3).

The SS310B is a schottky Diode made by MDD in a SMB(DO-214AA) package with 2 pins. -55℃~+150℃ 100V 300uA@100V 3A 850mV@3A Independent SMB(DO-214AA) Schottky Diodes ROHS.
PCBKit's library has its KiCad symbol (Diode:SS310, from KiCad's library) and its footprint (Diode_SMD:D_SMB, from KiCad's library), ready for a KiCad board. 97,639 are in stock at JLCPCB (part C14281). 2 open-source boards in 2 repositories on GitHub use it.
