The SpeedyBee F745 35A BLS 25.5×25.5 AIO Flight Controller is designed to provide a compact and integrated solution for small drones, where space is limited, and minimizing weight is crucial. This all-in-one flight controller aims to deliver high performance and convenience in a tiny package.
The SpeedyBee F745 AIO includes an F745 flight controller and a 35A ESC. Featuring a BMP280 barometer, OSD, 8MB Memory Blackbox, and MPU600 Gyro… this AIO board is the perfect addition to your FPV build.
Features:
Flight Controller:
F7 Processor: The flight controller typically features an F7 processor, offering advanced processing capabilities for smooth and precise flight control.
Integrated OSD (On-Screen Display): An integrated OSD allows you to overlay real-time telemetry data onto your FPV feed. This data can include battery voltage, flight mode, and other essential information.
Multiple UART Ports: The board often includes multiple UART ports for connecting peripherals like GPS modules, receivers, and telemetry devices.
Onboard BEC (Battery Eliminator Circuit): Some models have an onboard BEC, which provides a regulated power supply for your camera and video transmitter (VTX), reducing the need for external voltage regulators.
Betaflight or Cleanflight Support: The SpeedyBee F745 flight controller typically supports popular firmware options like Betaflight or Cleanflight, offering a wide range of flight features and customization options.
Blackbox Support: You can record flight data using the Blackbox feature for later analysis and tuning.
Electronic Speed Controllers (ESCs):
BLS (BLHeli_S) Firmware: The ESCs commonly feature BLHeli_S firmware, known for its reliability and performance. It supports popular communication protocols like DShot.
35A ESC Rating: The 35A ESC rating indicates that these speed controllers can handle a maximum current draw of 35 amps, making them suitable for micro and mini-sized drones.
Individual ESC Control: Each ESC is individually controlled, providing more precise motor control and diagnostics.
Telemetry Support: Some ESCs may offer telemetry support, allowing you to receive real-time information about the state of your motors and ESCs, including temperature and RPM.
25.5×25.5mm Form Factor: The stack is designed to fit a 25.5×25.5mm mounting pattern, which is a common size for micro and mini quadcopters.
Compact and Lightweight: The SpeedyBee F745 AIO Flight Controller is compact and lightweight, making it well-suited for small and lightweight drones.
