30A Electronic Speed Controller (ESC) for Brushless BLDC Motors

Overview

The 30A Brushless ESC is a high-performance speed controller designed for hobbyists and engineers alike. Whether you are building an FPV racing drone or an Arduino-controlled industrial turbine, this ESC provides smooth throttle response and reliable current delivery. It comes with a built-in BEC (Battery Eliminator Circuit), which outputs a stable 5V to power your flight controller or Arduino directly from the main flight battery—no extra buck converters needed!

Key Features 

• High Current Handling: Supports 30A continuous current and up to 40A burst (10 sec) for high-torque maneuvers.

• Built-in 5V/2A BEC: Powers your receiver and microcontrollers directly from the 3S LiPo battery.

• Safety First: Includes power arming protection (motor won’t spin if the throttle isn’t at zero) and overheat protection.

• Multi-Battery Support: Compatible with 2S and 3S LiPo packs, or 5-9 cell NiMH/NiCd batteries.

• Universal Compatibility: Works with any standard PWM signal from RC receivers, Arduino, or ESP32.
