The PCB is arrived and is tested. So far so good except a mark mistake. It works fine within 3Amps. Larger current haven’t test yet for lacking of suitable load. While using 3.3Vref, 10mR shunt and INA240V1(20x amp), the full scale is ±8.25A.
Schematic and PCB files are uploaded for anyone interested.
In case you dont know, ABI/UVW are external interrupt for sensor, PU/PV/PW are PWM output.
