The Readytosky 20A 2-4S Mini BLHeli-S OPTO ESC is a compact and high-performance electronic module integrated into the power distribution system of a drone. It is designed to provide precise control over the speed and performance of the drone’s motors. The “OPTO” designation typically means that this ESC lacks a built-in Battery Eliminator Circuit (BEC) to regulate and supply power to the flight controller and other onboard electronics. Instead, it’s designed to be used in setups where power distribution and regulation are handled separately.
Key Features:
Input Voltage Range: The ESC is compatible with input voltages ranging from 2S to 4S, making it suitable for a range of LiPo battery configurations. This flexibility allows users to adapt the ESC to different drones and voltage setups.
Current Rating: This ESC has a 20A current rating, which represents the maximum continuous current that each of its ESC channels can handle. The 20A rating is suitable for powering motors with varying current requirements.
OPTO Design: The OPTO designation means that this ESC doesn’t have a built-in Battery Eliminator Circuit (BEC) for powering the flight controller and onboard electronics. This design is preferred in setups where a separate BEC or voltage regulator is used to provide power to the flight controller and accessories.
Compact Form Factor: The compact size of the ESC is suitable for various drone frames and configurations, particularly smaller and lightweight drone designs.
High-Quality Components: The Readytosky series is known for using high-quality components to ensure reliability and efficient performance.
Advanced Motor Control: The ESC typically features advanced motor control firmware such as BLHeli or BLHeli-S, known for their reliability and performance. These firmware versions offer features like active braking and rapid response times.
PWM and DSHOT Compatibility: The ESC supports various control signal input options, including traditional PWM (Pulse Width Modulation) and DSHOT, a modern digital communication protocol. This flexibility allows users to choose their preferred control method.
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 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.
