Detailed Description:
This 20A ESC (Electronic Speed Controller) is a high-performance, low-cost controller designed to drive brushless DC (BLDC) motors used in quadcopters, drones, airplanes, and robotics projects. With its compact size, fast response, and reliable MOSFET switching, it ensures smooth motor operation and efficient power management.
The ESC supports both PWM input and one-shot protocols, and can be programmed via BLHeli or SimonK firmware (based on version). It's capable of handling up to 20A continuous current, with excellent thermal performance and overload protection.
Compatible with 2S–3S LiPo batteries, it is ideal for small to mid-size multirotors, offering great torque response, braking, and throttle control.
