Perhaps the Cheapest EVER way to get a 3 phase BLDC motor setup running - with a few extra wires and passives. Use each board for a phase - or make a classic H bridge with two of your PCB’s and have a spare half bridge lying around! Five bucks! Woo Hoo!!
D3 Bootstrap diode (1n4007), C9 Bootstrap cap (22uf). R19 Phase output resistor (for BLDC feedback & virtual ground). R9,10,11,12 Gate pullups/pulldowns as you measure apprioriate. SOIC 8 IR2110 - pin 1 denoted by Star.
Silk top layer markings: Phase/Vcc/Hi/Lo/Gnd. Staggered gate pin, Mask removed enabling Thickened Drain/Source (Phase) soldering.
Vcc needs to be 10-20v! Fet side voltages as per individual N Fet spec.
