Feature:1. Support voltage range 6.5-40V, undervoltage protection.2. Maximum load current 12A (no heat dissipation), 15A (simple heat dissipation), 20A (large heat sink).3. Instantaneous maximum current 110A for three-wire control of speed regulation, forward and reverse rotation and braking.4. Support full PWM, can directly control the forward and reverse using the button, PWM effective range 0.1%~100.0%.5. Can provide 5V power supply for MCU interface ESD protection.Specification:Item Type:DC Motor Drive BoardSize:5.5 x 5.5cm / 2.17 x 2.17inVoltage:6.5~40VApplicable Motor Type:Motor with rated voltage of 36V: suitable for rated power of 300W and below or rated current of 12A or less. The motor does not need to dissipate heat for a long time. The rated power is 300W~370W or the rated current is 12A~15A. The motor needs to be cooled. 370W ~ 500W or rated rated current 15A ~ 20A motor needs to do thick and large heat treatment;For motors with rated voltage of 24V, suitable for rated power of 200W and below or rated current of 12A or less, the motor does not need to dissipate heat for a long time. The rated power is 200W~250W or the rated current is 12A~15A. The motor needs to be simplified for heat dissipation; 250W ~ 330W or rated rated current 15A ~ 20A motor needs to do thick and large heat treatment;For motors with rated voltage of 12V, suitable for rated power of 70W and below or rated current of 12A or less, the motor does not need to dissipate heat for a long time. The rated power is 70W~90W or the rated current is 12A~15A. The motor needs to be cooled. 90W ~ 120W or rated rated current 15A ~ 20A motor needs to do thick and large heat treatmentPackage List:1 x Driver Board
