(as of 04/05/2017 at 15:51 UTC)


-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, otherwise easy to burn drive
-Note: Adjust the potentiometer with a special ceramic screwdriver. Otherwise, the drive is easy to be damaged
-The heat sink on the drive block is stuck to the middle of the chip (the other driver is the same), otherwise, it is liable to be shortened in current with the next pin.
