Description

The Flywoo GOKU F405 Nano Stack is engineered for high-density FPV racing and freestyle drones where space and weight are at a premium. Its integrated design combines a robust flight controller and a 35A 4-in-1 ESC into a single 16x16mm footprint, simplifying wiring and reducing build complexity. The STM32F405 processor handles Betaflight firmware with ample overhead for advanced filtering and features.

This stack is built for durability and performance, featuring a high-quality SPL06 barometer for altitude hold modes and programmable WS2812 RGB LEDs on each corner for low-profile orientation lighting. The ESC utilizes BLHeli_S firmware for reliable, smooth motor control across a wide 2-6S LiPo voltage range, making it suitable for both lightweight 3-inch and powerful 4-inch micro drone applications.

Key Features

  • High-Density Processing Core: STM32F405 BGA MCU provides the computational power needed for complex Betaflight filters and low-latency control loops.
  • Advanced IMU Sensor Suite: Primary ICM42688 gyro offers high-resolution, low-noise data for precise angle and rate control, with MPU6000 as a configurable backup.
  • Optimized Power Delivery: Integrated 4-in-1 ESC design minimizes power loop inductance and provides clean, stable current up to 35A per motor.
  • Extensive Connectivity: Six dedicated hardware UARTs enable simultaneous connection of modern digital VTX systems, ExpressLRS receivers, GPS modules, and telemetry without software multiplexing.
  • Professional-Grade Logging: 16MB of onboard flash memory allows for extensive blackbox recording at high sample rates to fine-tune PID filters and troubleshoot flight performance.
  • Modular Mounting System: Designed for direct pin-header connection to compatible Flywoo GOKU ESCs, but also includes solder pads for custom wiring to other 16x16mm ESC boards.

Applications

  • Ultra-compact 3-inch and 4-inch FPV freestyle and racing drones requiring a high-performance 16x16mm stack.
  • Lightweight micro long-range builds utilizing 4S or 6S LiPo batteries where space-saving integration is critical.
  • Advanced micro Cinewhoop platforms needing barometric altitude hold and extensive peripheral support (GPS, VTX control).
  • High-performance toothpick-class drones where the integrated 35A ESC provides ample overhead for aggressive 1404-1507 size motors.

Frequently Asked Questions

What is the maximum input voltage for this Flywoo GOKU stack?

The integrated 4-in-1 ESC is rated for 2-6S LiPo input, supporting a voltage range from approximately 7.4V up to 25.2V. This makes it suitable for high-performance micro builds running on 4S or 6S batteries. Always ensure your power wiring and connectors are rated for the corresponding current and voltage.

How many UARTs are available, and what can I connect to them?

This stack provides six dedicated hardware UARTs. Typical configuration uses one for your serial receiver (e.g., ExpressLRS, Crossfire), one for smart audio/tramp VTX control, one for a GPS module with compass, one for telemetry output, and leaves additional ports for peripherals like an airspeed sensor or LED strips. This extensive connectivity eliminates the need for softserial in most builds.

Is the flight controller pre-configured, or do I need to set it up in Betaflight?

The flight controller may come with a basic version of Betaflight installed, but you must perform a full setup. This includes configuring your receiver protocol, setting up motor resources, enabling the correct UART peripherals, and applying appropriate PID tunes for your specific drone. You should always update to the latest stable Betaflight release and use the 'FLYWOOF405NANO' target.

Can I use this stack with motors other than those specified by Flywoo?

Yes, the 35A 4-in-1 ESC is compatible with any brushless motor within its current and voltage ratings. It is well-suited for 1404, 1507, and similar sized motors used in 3-4 inch prop applications. Ensure your motor's maximum current draw, especially during peak thrust, does not exceed the 35A continuous rating per motor for reliable operation.
