This drive module performs much better than MC33886 or L298 motor drive module. T his drive module performs very well in terms of motor start speed and power efficiency. It can withstand high current overload. This drive has a brake function, which can quickly stop the motor. And the operation is very easy. Its performance is better than drive module of MC33886 chips. The drive module contains a full-bridge driver chip and MOSFET of low internal resistance. The full-bridge driver IC minimizes the switching loss of MOSFET and improves power efficiency. MOSFET driver chip has the hardware brake functions and power feedback function. MOSFET is the current impact-resistant type, with an internal resistance of 0.003 Euro. MOSFET channel can be opened quickly to improve the motor's speed curvature, and also brake the motor quickly. This function can make the car start or stop quickly. The drive module weighs 15 grams. It can work under the PWM duty cycle of 0% -98%, which a common drive module can not. Size:6cm x 4.5cm x 1.9cm - 2.36inch x 1.77inch x 0.75inch.
