Product Description The SimonK 30A BLDC ESC is a professional-grade speed controller specifically optimized for multirotor aircraft and high-performance drones. Pre-loaded with the renowned SimonK firmware, it offers an ultra-fast throttle response and smoother motor control compared to generic ESCs, which is essential for stable hovering and rapid aerial maneuvers. This "With Connectors" version comes with pre-soldered 3.5mm bullet connectors for the motor and typically an XT60 or T-type connector for the battery, making it a true plug-and-play solution for hobbyists.

Key Features

  • SimonK Firmware Optimized: Specifically engineered for multirotors to provide high-frequency throttle updates and reduced jittering.

  • Integrated 5V/2A BEC: Includes a Battery Eliminator Circuit to power your flight controller and radio receiver directly from the main battery.

  • Plug-and-Play Design: Features pre-installed high-quality connectors to eliminate the need for difficult soldering during assembly.

  • High-Efficiency MOSFETs: Utilizes low-resistance N-Channel MOSFETs to minimize heat generation and maximize flight time.

  • Advanced Protections: Equipped with backward-polarity protection and low-voltage cutoff to safeguard your electronics and LiPo batteries.

Technical Details

  • Dynamic Response: The SimonK firmware allows for refresh rates up to 433Hz, providing nearly instantaneous motor speed adjustments.

  • Wide Compatibility: Perfectly matched for A2212 series brushless motors (1000KV, 1400KV, and 2200KV).

  • Thermal Management: Built with a high-performance heat sink and transmission membrane to dissipate heat during aggressive flight.

  • Programmable Startup: Supports Normal, Soft, and Super-Soft start modes, compatible with both fixed-wing aircraft and multirotors.

  • Throttle Calibration: Easily adaptable to different transmitter throttle ranges for linear and predictable acceleration.

  • Signal Stability: The integrated microcontroller ensures stable operation even in high-interference environments.

  • Input Range: Reliable performance on 7.4V (2S) to 11.1V (3S) LiPo setups, supporting common drone power standards.

  • Active Braking: Provides sharper deceleration for more precise control during FPV racing or acrobatic flight.

  • Hardware Shielding: The PCB layout is optimized to reduce electromagnetic interference (EMI) with the flight controller.

  • High Burst Capacity: Can handle up to 40A for short durations (under 10 seconds) to support high-torque maneuvers.

  • Signal Input: Uses standard 1ms-2ms PWM pulse signals, making it compatible with Arduino, Pixhawk, and APM flight controllers.

  • Low Self-Discharge: Minimal static current draw ensures your battery isn't drained significantly when the system is idle.

  • Compact Footprint: Small enough to be mounted directly on the arms of 450mm and 500mm quadcopter frames.

  • Color Coding: Standard red/black power leads and yellow/red/brown signal wires for industry-standard wiring compliance.

  • Durable Outer Shell: Heat-shrink tubing protects the sensitive electronics from dust, moisture, and accidental shorts.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: Do not use a standard 9V alkaline battery to test this ESC. Brushless motors require high burst current that a 9V battery cannot provide, which may cause the ESC to reboot or enter a "low voltage" error state. Always use a high-discharge LiPo for testing.

  • 18650 Cell: For long-endurance ground vehicles, you can power this ESC using a 3S 18650 pack (11.1V). Ensure the cells are high-drain (at least 20A continuous) to prevent the battery voltage from sagging when the motor starts.

  • IC & Capacitor Tip: If you experience "desync" (the motor stuttering at high RPM), add a 470uF 25V Low ESR Capacitor at the battery input leads of the ESC. This helps smooth out voltage ripples caused by high-frequency switching. Always calibrate your throttle range through your flight controller's software (like Mission Planner or Betaflight) before the first flight.

  • Related Products: We recommend pairing this with our A2212 1000KV Brushless Motors, F450 Quadcopter Frames, and 1045 Nylon Propellers.
