Key features often found in quad driver modules include:
* Four independent H-bridges: These are circuits that allow for bidirectional control of the motor's rotation (forward and reverse). Each motor gets its own H-bridge.
* Current limiting: Protects the motors and the module itself from excessive current draw.
* Overheat protection: Shuts down the module if it gets too hot.
* Logic level inputs: Allows for easy control via microcontrollers like Arduino or Raspberry Pi. The voltage levels needed to control the module match the microcontroller's output voltage levels.
* Different voltage and current ratings: Modules are available with different specifications to handle motors with varying power requirements.
* Various interface options: Some might offer different communication interfaces like I2C or SPI for more complex control scenarios.
They are commonly used in robotics, automation, and other applications requiring the control of multiple motors. For example, a quadcopter drone might use a quad driver module to independently control each of its four rotors.
