An ESC (Electronic Speed Controller) module is a crucial component in drone systems, as it controls the speed of the motors and regulates the power distribution to the propellers.

The ESC module receives signals from the flight controller and adjusts the motor speed accordingly, allowing the drone to maneuver and maintain stability in the air.

Key features of ESC modules in drones include:

1. Motor control: ESCs regulate the speed of the motors, ensuring smooth and efficient operation of the drone.
2. Power distribution: ESCs distribute power to the propellers, ensuring that each propeller receives the appropriate amount of power for optimal performance.
3. Communication: ESCs communicate with the flight controller, receiving signals and adjusting motor speed accordingly.
4. Protection: ESCs often include protection features, such as overcurrent and overheating protection, to prevent damage to the drone and its components.
