Here’s a rewritten version in a more professional tone: “To build an autonomous iNAV Cinewhoop drone equipped with GPS capabilities.” While options for flight controllers are somewhat limited when it comes to AIO (all-in-one) designs, most models currently available on the market are characterized by a scarcity of UART ports or lack of support for iNav. Luckily, the Flywoo GOKU GN745 AIO V3 flight controller successfully addresses all my requirements. I’ll discuss my proficiency with this FC while upgrading my Betaflight drone to iNav configuration.

Should you consider purchasing the highly-regarded GOKU GN745 AIO V3 FC from a reputable supplier?

The package includes the following equipment:

• Unicon UPL Series 25V 470uF Ceramic Capacitor

Efficiency

The GOKU GN745 V3 leverages the STM32F745 microcontroller, AM32 firmware, and MPU6000 gyroscope to deliver exceptional performance and reliability. This versatile board features two identical binary-coded decimal (BEC) modules, a precision barometer, and a comprehensive black field layout, supporting seven serial ports and I2C connectivity to ensure seamless performance and versatility across diverse applications.

Plug & Play

This user-friendly flight controller is specifically designed to seamlessly integrate with the O3 air unit, GPS, digital camera, analog video transmitter, and receiver, eliminating the need for any soldering. This offers a fantastic option for both newcomers and seasoned customers seeking a seamless installation process.

Kind-C Interface

The V3 features a Kind-C interface, enhancing compatibility and streamlining connections, providing greater reliability compared to traditional Micro USB interfaces.

Compatibility

The GOKU GN745 V3 seamlessly integrates with various platforms, including Betaflight, iNav, and Ardupilot, providing unparalleled flexibility for users seeking to switch between distinct firmware options effortlessly.

New Structure

The ESC two-in-one drive’s advanced capabilities enable a constant supply of up to 45 amps, ensuring robust performance in even the most demanding scenarios.

Higher Safety

The V3 model boasts an enlarged motor pad area, significantly boosting overcurrent protection and subsequently reinforcing the robustness and dependability of the flight controller.

Replacing the flight controller within a short timeframe proved to be a straightforward process, thanks to the similarities in layout and capabilities between the two units.

While the Flywoo board offers additional JST model connectors, they come with both advantages and disadvantages. Despite this, the 4.5V BEC outputs are exclusively accessible via these connectors; the solder pads uniquely provide a 5V BEC. In addition, they provided 4.5-volt pads for soldering, enabling users to power devices from a USB connection without needing to plug in the LiPo battery.

What sets these modern all-in-one flight controllers apart is their provision of a conveniently accessible USB-C port, easily extendable via soldering pads for seamless integration with USB extension boards or adapters. For those who own a Cinewhoop, having the FC’s USB port hidden within the drone’s body can be quite inconvenient. By using a USB extension board or cable, connecting to Betaflight becomes remarkably effortless.

Notwithstanding its limitations, the GEPRC Taker G4 stands out by also exposing the Bootloader pad, a feature that significantly facilitates firmware updates. Since the Flywoo board lacks a dedicated boot button, I had to temporarily solder a jumper wire onto the board’s reset pin, as illustrated in the accompanying photo featuring an improvised connection.

Compared to the GEPRC Taker G4 All-In-One Flight Controller (AIO FC), the following features stand out.

As I work with the iNav system on this flight control (FC), utilizing GPS and a combination of rangefinder and optical movement sensors,

My goal is to design and build a first-person view (FPV) drone capable of maintaining a set location and altitude, similar to a DJI camera drone – a thrilling technical challenge! For extra element: 

The Flywoo GOKU GN745 45A All-In-One (AIO) Version 3 represents a significant leap forward in performance, incorporating advanced features that significantly enhance efficiency, prioritize safety, and provide unparalleled comfort. Its versatility in being compatible with multiple platforms, combined with its ease of use via plug-and-play capabilities, makes it an ideal choice for both novice and experienced FPV drone pilots alike.

Should you consider purchasing the GOKU GN745 AIO V3 FC from a reputable seller?

Whether upgrading a current drone or building a new one, the GN745 V3 provides the reliability and efficiency needed to elevate your first-person view (FPV) experience to unprecedented levels.
