The performance of this driver is unmatched by motor driver chips such as L298. This driver focuses on current and efficiency, effectively exerting motor power and battery life. It can withstand large current overloads, with a maximum current of 30A. This driver also has a function that can quickly brake the motor, with rapid and obvious , and it is easy to operate to achieve this function. This driver is composed of two complete half-bridge driver chips and extremely low internal resistance N-channel MOSFET. The reliable driving method of the complete two half-bridge driver chips minimizes the switching loss of MOSFET. MOSFET uses N-channel IRF3205 MOSFET, uses two dedicated half-bridge driver chips, and uses bootstrap capacitors for the upper tube, so that the upper tube has sufficient driving voltage, which can quickly open the MOSFET channel and increase the acceleration curvature of the motor. At the same time, it can also quickly brake the motor. This can enable the car to start quickly and kill quickly. This driver can operate at a PWM modulation duty cycle of 0percent -99percent , so that the motor can get enough driving voltage. Rated voltage: 3v-36v Rated current: 15A Motor forward: DIR=1 PWM=PWM Motor reverse: DIR=0 PWM=PWM Parking brake: DIR=X PWM=0 (X is Any state) POWER is connected to the positive pole of the power supply, GND is connected to the negative pole of the power supply. The two motors are connected to MOTOR1 and MOTOR2 respectively Different batches may have different appearance label printing, which not affect the use Colour:Green Material:plastic Package Contents: 1 x DC Motor Driver Module Only the above package content, other products are not included.
