The SpeedyBee F405 V3 BLS 50A 30x30 Stack is a comprehensive flight control system designed for drones, integrating a flight controller (FC) and an electronic speed controller (ESC) into a compact stackable unit. This manual, version V1.0, provides detailed information on its specifications, connections, configuration, and maintenance.
The SpeedyBee F405 V3 BLS 50A 30x30 Stack serves as the central brain and power distribution unit for a drone. The Flight Controller (FC), the SpeedyBee F405 V3, processes flight commands, stabilizes the drone, and manages various peripherals. It runs on BetaFlight, EmuFlight, or INAV firmware, offering extensive customization and control options. The Electronic Speed Controller (ESC), the SpeedyBee BLS 50A 4-in-1 ESC, is responsible for converting the FC's commands into motor speed adjustments, driving up to four motors simultaneously. The "4-in-1" designation means it integrates four individual ESCs onto a single board, simplifying wiring and reducing weight. The stack design allows for a compact and organized build, crucial for drone applications where space and weight are at a premium.
Product Name: SpeedyBee F405 V3 BLS 50A 30x30 Stack
The FC and ESC are connected via an 8-pin cable (included) or by direct soldering 8 wires to the designated pads. This modular approach offers flexibility in assembly. The FC supports a wide range of peripherals including FPV cameras, a second 4-in-1 ESC, receivers (PPM, SBUS, Crossfire Nano Rx), extra PWM outputs, GPS & Compass modules, Betaflight LEDs, VTX (Analog/DJI), and buzzers. It also features a dedicated DJI Air Unit Connector for seamless integration with DJI FPV systems.
The SpeedyBee F405 V3 FC includes a Bluetooth chip, enabling wireless configuration of both the FC and ESC parameters via the SpeedyBee mobile app. This eliminates the need for a PC connection for many common adjustments, offering convenience in the field.
The FC features several LED indicators:
The BOOT button serves two primary purposes:
It's important to note that wireless blackbox download & analysis and wireless FC firmware flashing are NOT supported by this stack. FC firmware updates must be performed via a PC connection.
The ESC can be configured wirelessly using the SpeedyBee app or via a PC using the ESC Configurator software.
The product is available in three options:
To prevent damage from voltage spikes during power-up, it is strongly recommended to use the included 35V 1500uF Low ESR Capacitor. This capacitor helps smooth out power delivery and protect the sensitive electronics.
The package includes M3 silicone O-rings, M38mm silicone grommets for the FC, and M38.1mm silicone grommets for the ESC. These components help absorb vibrations and protect the boards from physical stress during mounting and flight. The TVS diode on the ESC also provides protection against transient voltage spikes.
The BOOT button serves as a critical tool for recovery if the flight controller becomes bricked, allowing users to force it into DFU mode for firmware re-flashing.
The SpeedyBee F405 V3 BLS 50A 30x30 Stack is designed for both ease of use and high performance, catering to drone enthusiasts and builders who require a reliable and feature-rich flight control system.
