Description

The BotStack F405 FC and AM32 ESC combo provides a robust foundation for modern FPV drones. The flight controller features a 32-bit STM32F405 processor paired with a high-precision ICM42688P gyro, delivering responsive handling and stable flight characteristics. Its solderless architecture utilizes plug-in connectors for motors, power, and peripherals, significantly reducing build complexity and potential wiring faults.

The paired BotDrive 4-in-1 ESC leverages open-source AM32 firmware on an AT32F421 MCU, offering 55A continuous current per motor with support for DShot600 telemetry. This electrical design ensures minimal latency and precise throttle response across a 2S-6S LiPo input range. The stack’s 30.5×30.5mm mounting pattern and integrated power distribution make it ideal for compact, high-performance quadcopter builds requiring reliable power management and thermal capability.

Key Features

  • Solderless Flight Controller with plug-in JST connectors for clean, reliable assembly.
  • High-Current AM32 ESC Firmware for smooth motor operation and enhanced energy efficiency.
  • Onboard AT7456E OSD and 32MB Blackbox logging for real-time data and post-flight analysis.
  • Dual BEC Outputs (5V & 9V) to power FPV cameras, VTXs, and other accessories.
  • Wide Input Voltage Range (2S-6S for ESC, 3S-6S for FC) for versatile battery compatibility.
  • Compact 30.5x30.5mm Stack Form Factor with vibration-damping silicone grommets.
  • Direct DJI Digital FPV Air Unit support via dedicated plug-and-play connector.

Applications

  • 5-inch FPV Racing Drones requiring low-latency control and high-current ESCs.
  • Freestyle Quadcopters benefiting from the solderless design for easy maintenance and rebuilds.
  • Cinematic FPV Drones utilizing the onboard OSD, Blackbox, and GPS support for stabilized flight.
  • High-Performance Builds using 6S LiPo batteries demanding robust 55A continuous current delivery.
  • Betaflight & iNav-based platforms leveraging the six UARTs for extensive peripheral connectivity.

Frequently Asked Questions

What is the input voltage range for this FC and ESC stack?

The flight controller accepts 3S to 6S LiPo input (approximately 9V to 25.2V), while the 4-in-1 ESC supports a wider range of 2S to 6S LiPo (7.4V to 25.2V). This allows for flexibility in battery selection, from lighter 2S setups to high-power 6S configurations.

Is the flight controller truly solderless?

Yes, the BotWing F405 FC uses a solderless design with plug-in JST connectors for motor signals, battery input, receiver, and peripherals like the DJI Air Unit. This design eliminates soldering for most connections, making assembly faster and reducing the risk of wiring errors.

Which firmware is pre-installed on the ESC?

The BotDrive 4-in-1 ESC comes pre-flashed with the open-source AM32 firmware, specifically version AM32_AT32PB4_540_F421 for the AT32F421 MCU. This firmware supports advanced features like bidirectional DShot telemetry, high PWM frequencies, and tunable motor timing.

Can I use this stack with DJI Digital FPV systems?

Yes, the BotWing F405 flight controller includes a dedicated plug-and-play connector for the DJI Air Unit (or CaddxFPV Vista), providing both power and data communication without requiring additional wiring or soldering.

What mounting pattern does this stack use?

Both the flight controller and the 4-in-1 ESC share a standard 30.5mm x 30.5mm mounting hole pattern with M3 screws. The package includes silicone and rubber grommets for vibration-damping installation in your drone frame.
