The AcodaRc 35A 2-5S BLHeli_S 4-in-1 ESC is a compact electronic module that combines four individual electronic speed controllers into one unit. It is designed to provide precise control and management of the motor speeds in a quadcopter or other multirotor drone. This specific model is capable of handling input voltages ranging from 2S to 5S, which makes it compatible with a variety of drone setups.

This 4-in-1 35A 2-5S BLHELI_S ESC speed controller is presented as one of the budget options for ESC 4-in-1 speed controllers of this kind.

Key Features:

Input Voltage Range: The ESC is compatible with input voltage ranges from 2S to 5S, which covers a wide range of LiPo battery configurations. This flexibility allows users to adapt the ESC to different drones and voltage setups.

BLHeli_S Firmware: The BLHeli_S firmware is a popular and well-regarded ESC firmware known for its reliability and performance. It offers features like active braking and excellent response time, which are crucial for precise control and smoother flight.

Current Rating: This ESC has a 35A current rating, which represents the maximum continuous current that each of its four ESC channels can handle. It’s essential to choose an ESC with a current rating that matches the power requirements of your drone’s motors.

4-in-1 Design: The 4-in-1 design means that four individual ESCs are combined into a single module. This setup reduces the number of individual components in your drone, simplifies wiring, and can lead to cleaner and more organized builds.

Compact Form Factor: The compact size of this ESC makes it suitable for smaller drone frames with limited space. Its small footprint allows for easier integration into the drone’s frame.

DShot Support: This ESC typically supports DShot communication protocol, which provides digital communication between the flight controller and the ESC. DShot is known for its precision and efficiency in transmitting motor control commands.

Built-In BEC: Some 4-in-1 ESCs come with a built-in Battery Eliminator Circuit (BEC) that provides a regulated 5V output to power the flight controller and other onboard electronics.

On-Board Protection: Many modern ESCs include protection features like over-current protection, thermal protection, and motor lock-up detection to safeguard the ESC and your motors from damage in the event of a malfunction.

Motor Connectors: The ESC typically includes connectors for attaching the motor wires and a power input lead to connect to the drone’s battery.

Signal Input: The ESC receives control signals from the flight controller through a compatible signal input connection, such as a PWM (Pulse Width Modulation) or DShot input.
