FAQs

Can I charge battery using this module?

No. To charge batteries, you need a power supply with controlled voltage and current. This module is designed to control the DC motors.

Can I drive a DC motor with Arduino without using such motor driver modules?

No. Most of microcontrollers capable of handling up to 100~200mA current totally on all pins. That means each pin can handle just about 25mA. Generally, such current is not enough to drive DC motors.

Is the BTS7960 suitable for bidirectional motor control?

Yes, the BTS7960 is configured as an H-bridge, enabling bidirectional control of DC motors. This means you can control the motor in both forward and reverse directions.

Can I use this module to build a radio controlled drones?

While the BTS7960 43A High Power Motor Driver Module is suitable for motor control in various applications, it may not be the most appropriate choice for building a radio-controlled drone. Drones, especially multirotor aircraft like quadcopters, have specific requirements that go beyond what the BTS7960 module provides. Here are some considerations:

Motor Type: The BTS7960 is designed for DC motors, and typical drones use brushless DC motors. Brushless motors require Electronic Speed Controllers (ESCs) that are specifically designed for them. These ESCs often include features like motor timing adjustment and are more suited for high-speed and dynamic applications.
Motor Control Precision: Drones require precise motor control for stable flight and maneuverability. Dedicated drone ESCs are designed to handle the rapid changes in motor speed required for aerial maneuvers. They often incorporate advanced algorithms and control mechanisms to achieve stability.

If you're looking to build a radio-controlled drone, it's recommended to use dedicated drone ESCs that are compatible with brushless DC motors and designed to work seamlessly with drone flight controllers. Additionally, consider an integrated flight controller that supports your specific drone application.
