Layout
The layout diagram illustrates the top and bottom views of the SpeedyBee F745 35A BLS AIO board. It labels various components and connectors, including the MCU (STM32F745), IMU (MPU6000), Barometer (BMP280), Bluetooth/WiFi chip, UART ports (UART1-4), I2C pads (for Compass/Receiver), Camera connector, DJI Air Unit connector, USB port pads (D+, D-, GND), LED pads, Buzzer pads (BZ+, BZ-), BOOT button, and motor outputs (Motor 1-4). It also details LED indicator definitions: GREEN LED - Solid Green indicates Bluetooth is connected; BLUE LED - Flight controller status light controlled by the firmware. Instructions for the BOOT Button are provided: hold the button and power the FC simultaneously to enter DFU mode for firmware recovery, then use the SpeedyBee app to re-flash.
Part 2 - Flight Controller
Wiring Diagram
The wiring diagram shows how to connect various peripherals to the SpeedyBee F745 35A BLS AIO. It details connections for GPS (5V, TX, RX, GND), Camera (5V, GND, Video, CC), Spectrum Receiver (5V, GND, PPM), SBUS Receiver (5V, GND, SBUS), Crossfire Nano Rx (5V, GND, TX, RX), DJI Air Unit (5V, GND, Video, TX, RX), and Analog VTX (5-36V, GND, Video). It also shows connections for a Buzzer (BZ+, BZ-) and LED Stripe (5V, GND, LED). A note clarifies that the USB-C module requires external power from a battery before connecting to a computer.
App Usage
The SpeedyBee app can be downloaded from Google Play or the App Store, or via an .apk file from the SpeedyBee website: https://www.speedybee.com/download. The app allows connection to the SpeedyBee F745 AIO via Bluetooth or Wi-Fi. The 'Connect the App' section shows screenshots of the app interface, including a 'Flight Time World Ranking' screen, a dialog to find and connect to the SpeedyBee F745 AIO, and a 'Setup' screen displaying flight parameters like Battery Voltage (e.g., 15.84V), RSSI, GPS status, and options for calibration (Accelerometer, Magnetometer).
FC Firmware Update
The FC Firmware Update section guides users through updating the flight controller firmware using the SpeedyBee app. The process involves three steps: 1. Load Firmware (selecting firmware type and source, e.g., Betaflight, INAV), 2. Connect Flight Controller and App (selecting device type, e.g., SpeedyBee F7 AIO, and establishing a connection via Bluetooth/Wi-Fi), and 3. Flash Firmware (initiating the flashing process). Screenshots illustrate these steps within the app, showing progress indicators and success messages.
BlackBox Analyzer
The BlackBox Analyzer feature allows users to load and analyze flight log data. Users can access this function through the SpeedyBee app, selecting 'Blackbox Analyzer' and then choosing to load logs from the flight controller's built-in flash memory or SD card. Screenshots show the app interface for selecting the analyzer and connecting to the FC.
Part 3 - ESC
Connection with Motors & Power Cable
This section illustrates the connection of motors to the ESC outputs (Motor 1-4) and the power input via the XT30 connector. It includes a critical note ?: "In order to prevent the AIO from being burnt out instantaneous voltage spikes on powering up, it is strongly recommended to use the Low ESR capacitor in the package."
ESC Configuration
The ESC Configuration section details how to configure the ESC settings using the SpeedyBee app. Users first initiate the ESC Configurator, select a connection method (Wi-Fi or Bluetooth), and connect to the SpeedyBee F745 AIO. The app provides options to 'Read' current ESC settings and 'Save' new configurations. General settings include 'Startup Power', 'Temperature Protection', 'Low RPM Power Protection', 'Brake on stop', 'Demag Compensation', and 'Motor Timing'. Users can also adjust 'Beep Strength' and 'Beacon Delay'. The interface allows for reading and writing settings, flashing firmware, and testing motors. It also shows parameters like ESC version (e.g., ESC 1: J-H-40-FLEX25, 16.7) and motor direction settings.
ESC Firmware Update
This section explains how to update the ESC firmware, supporting both BLHeli_S and Blue Jay firmware. The process involves connecting the AIO to a PC via USB after powering it with a battery, and then using the online configurator at https://esc-configurator.com/. The note specifies that the ESC Type should be set to 'J-H-40'. The screenshots show the ESC Configurator interface, including port selection, connection, and firmware flashing options, with parameters like motor direction and firmware version.
