Description

The SpeedyBee F405 V4 BLS stack combines a robust flight controller and electronic speed controller into a single 30x30mm unit, engineered for demanding FPV applications. The FC utilizes an STM32F405 microcontroller paired with an ICM42688P gyro for precise attitude control and low-latency response, essential for racing and acrobatic maneuvers.

The integrated 4-in-1 ESC delivers 60A continuous current per motor with BLHeli_32 firmware, enabling advanced features like bidirectional DSHOT telemetry and smooth throttle resolution across a 3-6S LiPo input range. The stack’s design prioritizes thermal management and electrical integrity, ensuring reliable performance during prolonged, high-current flight sessions.

Key Features

  • High-performance STM32F405 flight controller with ICM42688P IMU for precise flight dynamics.
  • BLHeli_32 4-in-1 ESC rated for 60A continuous (80A burst) current per motor output.
  • Wide 3-6S LiPo battery compatibility with integrated current sensing capability.
  • Compact 30x30mm stack design with efficient heat dissipation for racing builds.
  • Type-C USB port, built-in barometer, and AT7456E-based OSD for full telemetry.
  • Firmware support for Betaflight and INAV with configurable UARTs for GPS and peripherals.
  • Buzzer and LED output support for in-flight alerts and status indication.

Applications

  • 5-inch FPV racing drones requiring high-current ESC performance and low-latency flight control.
  • Freestyle quadcopters utilizing 3-6S LiPo batteries for aggressive acrobatic maneuvers.
  • Betaflight or INAV-based builds needing integrated barometer and current sensor telemetry.
  • Compact 30x30mm frame builds where space optimization and stack reliability are critical.

Frequently Asked Questions

What is the maximum input voltage for the SpeedyBee F405 V4 BLS stack?

The stack supports a 3-6S LiPo input voltage range, corresponding to approximately 9V to 25.2V. Ensure your power source stays within this range to prevent damage to the ESC and flight controller components.

Which flight firmware is compatible with this FC & ESC stack?

The flight controller is compatible with Betaflight and INAV firmware. The integrated 4-in-1 ESC runs BLHeli_32 firmware, which supports bidirectional DSHOT telemetry and can be configured via the BLHeliSuite32 configurator tool.

What is the mounting pattern and are any standoffs included?

The stack uses a standard 30x30mm mounting pattern with M3 screw holes. The package includes the stack itself; you will need to source appropriate M3 standoffs and screws separately to mount it to your drone frame.

Does this stack have a built-in current sensor and how is it calibrated?

Yes, it features a built-in current sensor. The default scale is set to 400 with an offset of 0. You can fine-tune the calibration within your flight firmware (Betaflight/INAV) using battery current readings from a trusted external meter for optimal accuracy.
