NZFPV Hakrc F4551 Flight Controller

Advanced Flight Control and Sensors

The HAKRC F4551 Flight Controller is equipped with the STM32F405RGT6 CPU and ICM42688 Inertial Measurement Unit (IMU) for accurate flight data processing. Running the HAKRC F405V2 firmware, it includes an AT7456E chip for On-Screen Display (OSD), an integrated barometer for altitude hold, and a 16MB black box for flight log recording. The board features a 5V/4A BEC and 12V/3A BEC for robust power delivery, six serial ports for enhanced connectivity, and an in-line programmable magic color LED for customizable lighting effects.

High-Quality PCB Construction

Built on a high-end 6-layer PCB with 1oz copper skin and resin-plugged hole technology, the F4551 ensures strong anti-interference and superior durability. Industrial-grade LDOs provide high-temperature resistance, and high-quality Japanese Murata capacitors deliver exceptional filtering performance. This robust construction guarantees reliable performance in demanding FPV and RC environments.

Compact and User-Friendly Design

Measuring 36mm x 36mm with 30.5mm x 30.5mm mounting holes, the F4551 is designed for seamless integration into various builds. Weighing 8.5g, it uses in-line connectors for solder-free, easy installation and includes multiple seats for time-saving operation. Supporting 2S-8S LiPo batteries, the board provides 8 motor outputs for versatile quadcopter or multi-rotor setups and is compatible with multiple receiver protocols, including Frsky, Futaba, Flysky, TBS Crossfire, and DSMX/DSM2.

Enhanced User Experience

The HAKRC F4551 Flight Controller elevates the RC experience with:

• Simplified Installation: In-line connectors and multiple seats eliminate soldering, reducing wiring complexity for clean, efficient builds.
• Precise and Stable Flight: The STM32F405 CPU and ICM42688 IMU deliver smooth, responsive flight performance with reliable control algorithms.
• Comprehensive Features: Built-in OSD, barometer, 16MB black box, and programmable magic color LED provide essential flight data, altitude hold, logging, and customization without extra modules.
• Robust Power Management: Dual BECs (5V/4A and 12V/3A) support power-intensive setups while maintaining stability.
• Wide Compatibility: Supports multiple receiver protocols (Frsky, Futaba, Flysky, TBS Crossfire, DSMX/DSM2), 2S-8S LiPo input, and six serial ports for flexible RC applications.
• Customizable Lighting: In-line programmable magic color LED allows seamless switching of lighting effects for enhanced personalization.
