Holybro Tekko32 F4 45A AM32 2–6S ESC

Product description

The Holybro Tekko32 F4 45A AM32 ESC is a modern single-ESC designed for high-performance FPV drones and is aimed at pilots seeking maximum control, fast signal processing, and reliable performance in the smallest possible space. Equipped with a powerful F4 microcontroller, modern AM32 firmware, and support for 2–6S LiPo batteries, this ESC delivers an extremely direct and clean flying experience—ideal for racing, freestyle, and ultralight high-performance builds.

Thanks to the fast ARM 32-bit F4 processor, the Tekko32 processes signals with exceptionally low latency and supports modern protocols such as DShot1200 at up to 32 kHz. The PWM frequency of up to 48 kHz ensures smoother motor operation, improved efficiency, and more responsive throttle response. From a physical standpoint, this is simply elegant electromagic: less ripple, more control, and fewer moments of “Why does my quad sound like an angry vacuum cleaner?”

The integrated current sensor enables precise current monitoring directly via the flight controller. Additionally, the AM32 firmware offers extensive customization options such as brake-on-stop tuning, RPM optimization, and voltage and current monitoring.

Weighing just 5.8g and featuring compact dimensions, the Tekko32 F4 45A is perfect for lightweight freestyle and racing frames where every gram counts. Despite its small form factor, the ESC delivers a powerful 45A of current and remains reliable and efficient even under load.
