Specifications:
-Net Weight: 10g/pcs
-Pros: Super quiet
-Drive current algorithm: i = Vref * 1.9 / 2.5, the default Vref about 0.65v, so the default current is 0.5A, maximum current is1A
-When measuring voltage must not be connected to the motor, otherwise it will easy to burn drive
-When measuring voltage power, do not just connect the USB power supply
-When measuring voltage must not be connected to the motor
