The “BLHeli_32 35A 4-in-1 2-4s w/ BEC 3A/12v, 1A/5v, DSHOT 1200” is an electronic speed controller (ESC) designed for multirotor drones, particularly quadcopters, hexacopters, and octocopters. Here’s a breakdown of its key features and specifications:

1. Brand and Model:

  • BLHeli_32: Indicates the firmware protocol used by the ESC. BLHeli_32 is a popular firmware option known for its advanced features and performance.
  • 35A 4-in-1: This refers to the current rating and configuration of the ESC. It can handle a maximum continuous current of 35 amps per channel and is configured as a 4-in-1 ESC, meaning it integrates four individual ESCs into a single unit for easier installation and wiring management.

2. Voltage Input Range:

  • 2-4s: Indicates the compatible voltage input range of the ESC, which is suitable for 2 to 4 cell LiPo batteries. This range covers common voltage configurations used in multirotor drones.

3. Built-in BEC (Battery Eliminator Circuit):

  • 3A/12v, 1A/5v: The built-in BEC provides regulated voltage output to power auxiliary components such as flight controllers, receivers, and other onboard electronics. It offers two voltage options: 3 amps at 12 volts and 1 amp at 5 volts.

4. Communication Protocol:

  • DSHOT 1200: DSHOT is a digital communication protocol used for transmitting throttle commands from the flight controller to the ESCs. DSHOT 1200 is a high-speed version of DSHOT, offering low latency and improved signal accuracy.

5. Features:

  • High Current Rating: With a maximum continuous current rating of 35 amps per channel, this ESC can handle high-power applications and aggressive flight maneuvers.
  • Advanced Firmware: BLHeli_32 firmware offers a wide range of features, including motor timing adjustment, active braking, ESC telemetry, and configurable startup tones.
  • Integrated BEC: The built-in BEC eliminates the need for a separate voltage regulator, reducing weight and simplifying the wiring setup.

6. Compatibility:

  • Flight Controller Compatibility: Compatible with various flight controllers that support DSHOT protocol, ensuring seamless communication and compatibility with modern drone setups.
  • Motor Compatibility: Compatible with a wide range of brushless motors commonly used in multirotor drones.


The BLHeli_32 35A 4-in-1 ESC with built-in BEC and DSHOT 1200 protocol offers high performance, reliability, and ease of installation for multirotor drones. With its high current rating, advanced firmware features, and integrated voltage regulation, it provides a robust solution for powering and controlling the motors in your drone build. Compatible with various flight controllers and motors, it’s suitable for a wide range of applications, from racing drones to aerial photography platforms.
