ULN2003 Stepper Motor Driver Board Module In Pakistan

The Double BTS7960 43A H-Bridge High-Power Stepper Motor Driver Module is; a fully integrated high current H bridge for motor drive applications using the BTS7960 high current half-bridge. the BTS7960 is part of the NovalithICTM family. This contains one p-channel high side MOSFET and one n-channel low side MOSFET; with an integrated driver IC in one package. Due to the p-channel high side switch; the need for a charge pump is eliminated thus minimizing EMI. Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs; diagnosis with current sense, slew rate adjustment; dead time generation and protection against overtemperature, overvoltage, under-voltage; overcurrent, and short circuit. The Double BTS7960 43A H-Bridge High-Power Stepper Motor Driver Module provides; a cost-optimized solution for protected high current PWM motor drives with very low board space consumption.

This L298N Based Motor Driver Module is a high-power motor driver perfect for driving DC Motors . H Bridge Driver Module uses the popular L298 motor driver IC and has the onboard 5V regulator which it can supply to an external circuit. It can control up to 4 DC motors, or 2 DC motors with directional and speed control. This Motor Driver is perfect for robotics and mechatronics projects and perfect for controlling motors from microcontrollers, switches, relays, etc. Perfect for driving DC for micro mouse, line-following robots, robot arms, etc. An H-Bridge is a circuit that can drive a current in either polarity and be controlled by Pulse Width Modulation (PWM). Pulse Width Modulation is a means of controlling the duration of an electronic pulse. In motors try to imagine the brush as a water wheel and electrons as the flowing droplets of water. The voltage would be the water flowing over the wheel at a constant rate, the more water flowing the higher the voltage. Motors are rated at certain voltages and can be damaged if the voltage is applied too heavily or if it is dropped quickly to slow the motor down. Thus PWM. Take the water wheel analogy and think of the water hitting it in pulses but at a constant flow. The longer the pulses the faster the wheel will turn, the shorter the pulses, the slower the water wheel will turn. Motors will last much longer and be more reliable if controlled through PWM.
