Electronic speed controller ESC 40A for brushless motors (2S-4S LiPo, BEC 5V/3A)

Brushless ESC 40A for smooth speed control of 3-phase BLDC motors. Power and reliability: Handles continuous current up to 40 A (short-term up to 55 A), ideal for model aircraft, model boats and quadcopters. Built-in BEC: Outputs 5 V / 3 A via the control cable, allowing you to power a flight controller, radio receiver or Arduino board without a separate power source. Servo protocol control: Controlled by standard servo signals (Servo.h library in Arduino), ensuring maximum simplicity of connection and setup. Features Current — 40 A (continuous), up to 55 A (peak for up to 10 sec) Motor type — Brushless 3-phase (BLDC) Power — 2S – 4S LiPo (7.4 V – 14.8 V) or 5–12 cells NiMH Built-in BEC — 5 V / 3 A (power for receiver / microcontroller) Control signal — Standard PWM / Servo PWM (1000–2000 μs, 50 Hz) Power wires — Red (+), Black (-) Phase wires — 3 blue wires Control connector — 3-pin JR (Signal, VCC 5V, GND)
