The 30A Electronic Speed Controller (ESC) is a high-efficiency, compact speed controller for brushless BLDC motors, supporting 2S–4S LiPo batteries. Preloaded with SimonK or BLHeli firmware, it ensures ultra-fast throttle response, linear acceleration, and excellent motor synchronization. Ideal for DIY drones, RC planes, quadcopters, and robotic projects, this ESC includes a 5V/2A BEC, enabling direct power supply to flight controllers or servos.
