Achieve the legendary “KISS flight feel” with the Flyduino KISS 25A 4-in-1 ESC. This premium 32-bit electronic speed controller is engineered for pilots who demand the absolute smoothest and most responsive performance from their FPV drone. Paired with a KISS flight controller, this ESC provides a complete, seamlessly integrated power system with unparalleled control.

The Legendary KISS Experience This ESC, powered by a 32-bit ARM Cortex M4 MCU running at $80\text{MHz}$, is the key to the famously smooth and locked-in flight characteristics of the KISS ecosystem. It provides full, real-time telemetry data (voltage, current, temperature, RPM) and is designed for a simple, clean, plug-and-play connection to your KISS flight controller.

Advanced Technology for Smooth Power The KISS 25A ESC is packed with proprietary technology to deliver superior performance.

• sinHybrid Commutation: A unique Sinwave/BackEMF hybrid commutation method results in exceptionally smooth motor operation, reducing vibrations and improving efficiency.
• DShot 2400 Support: With a full resolution of 2000 steps, this high-speed protocol provides incredibly precise throttle control and a near-instant response feel.

Robust & Reliable by Design Engineered for reliability, the ESC features over-current and over-temperature protection, actively limiting power to prevent damage. The 6-layer, $70\text{µm}$ copper PCB and a massive amount of onboard ceramic capacitors ensure stable power delivery, eliminating the need for an external capacitor on most 3S-5S builds.

Key Features:

• Legendary KISS Flight Feel: Proprietary 32-bit firmware provides an incredibly smooth, responsive, and intuitive flight experience.
• sinHybrid Commutation: A unique technology that results in smoother, more efficient motor performance.
• Full Telemetry Support: Transmits real-time voltage, current, temperature, and RPM data to your KISS flight controller.
• 25A Continuous Power: Provides reliable power ($40\text{A}$ burst) for most 5-inch freestyle and racing motors on up to 5S.
• Advanced Protection: Features active over-current and over-temperature protection to safeguard your electronics.
• High-Quality Construction: A 6-layer PCB and a large bank of onboard capacitors ensure robust, reliable power delivery.
