Feature: 1. Can independently control two motors, each channel can output 5A, top 9A, standby current is only 10uA. 2. The wide power supply range is 3-14V, the signal power supply range is 2.2-6V, and the 3.3V and 5V levels can be satisfied. 3. The board provides 3.3V 100mA power supply to meet the power consumption of your control system. 4. Two-way H-bridge motor drive, can drive two DC motors or one 4-wire two-phase stepper motor at the same time. 5. There is a printing prompt on the back of the circuit board to indicate the pole. Specification: Item Type:Dual Motor Drive Module Power Supply Module:3~14V Installation Hole Diameter:2mm / 0.08in Weight: 14 g / 0.49 oz(approx.) Package List: 1 x Driver Module Note: When the motor is commutating, it must wait for the motor to stop first, otherwise the instantaneous current will burn out the module driver chip.The exposed pins on the back of the board must not be short-circuited, otherwise permanent damage may occur.Do not connect the positive and negative poles of the power supply, otherwise it will burn out.There is a printing prompt on the back of the circuit board.
