Featureļ¼ 100% brand new and high quality Equipped with a large heat sink, the heat dissipation effect is good, it supports the UART mode without jumper, the driving current is large, and the current can reach 2.0A.
Drive current algorithm: 1. Vref measures Gnd and the voltage at the middle end of the potentiometer 2. When measuring voltage, be sure not to connect the motor, otherwise it is easy to burn the drive 3. When measuring the voltage, the power should be turned on, don't just connect the USB power supply 4.I=Vref, default I=1.25A
