Introduction Overview The BOYING DRACO Series is a comprehensive suite of industrial autopilot flight controllers designed for a wide range of UAV applications, from compact mapping drones to large-scale heavy-lift platforms. Fully compatible with PX4 open-source firmware, the DRACO series offers exceptional versatility, precision, and reliability, supporting both standard and advanced multirotor configurations. From integrated power modules to seamless GNSS RTK positioning, the DRACO ecosystem enables plug-and-play deployment with intuitive wiring and robust interface management. Key Features Voltage Input: 6S28S (model dependent) CAN Interfaces: Single or dual CAN buses PWM Outputs: 8 to 16 depending on model Operating Temperature: -20C to 70C Hover Accuracy: 0.5m (horizontal and vertical) Maximum Inclination Angle: 35 PX4 Firmware Compatibility: Supports multirotor, VTOL, helicopter, boat, and car types Cloud Platform: Integrated with BOYING Industrial Bit Data Cloud Advanced Modular Design Independent ports for all modules, including GNSS, RTK, power input, telemetry, LEDs, and CAN extensions XT30 power port on select models like DRACO MINI2 for direct 614S battery connection Anti-reverse plug design for main and auxiliary connectors simplifies installation and eliminates error Platform Compatibility Supports clockwise, counter-clockwise, and asymmetric multirotor configurations: X4, 4 X6, 6 X8, 8 Coaxial X4 and 4 4 propeller systems Asymmetric models: 3 3, 4 2, 4 4, and more System Expansion & Peripherals The DRACO controller natively supports integration with: Dual-band GNSS modules RTK positioning systems 360 omnidirectional LiDAR Edge onboard computing systems Gimbal cameras High-voltage ESCs PWM signal I/O S.BUS receiver input 4G data transmission modules LED Status Indicators The integrated LED provides at-a-glance system status and diagnostic feedback: LED Behavior Indication No light LED fault or log update Red/White alternate flashing FC initializing Red/Yellow/Blue/Green flash No device calibration Red/Blue/Green flashing Calibration/testing in progress Yellow slow flash RC fault or low voltage protection Purple solid Compass fault Purple dual flash Accelerometer fault Purple fast flash Unlock failure or init incomplete Red solid Log memory failure Red/Yellow alternate GPS failure Blue solid or flashing No GPS Green solid or flashing GPS locked Green fast flashing High-precision GPS lock Remote Controller S.BUS Channel Mapping The DRACO autopilot system fully supports S.BUS receivers. For common transmitters, channel assignments are preconfigured: Channel Function Notes 1 Roll 2 Pitch 3 Throttle 4 Yaw 5 Flight Mode Used for flight mode switching and calibration 6 Aux1 Preconfigured auxiliary channel 7 Return-to-Home Also used as failsafe trigger (value 975) 8 AB Switch Enables AB path function 914 Auxiliary Optional programmable inputs For receivers without clear failsafe status on throttle, Channel 7 must be configured as the failsafe trigger. Flight Controller Installation Guidelines Installation Orientation: Align FC with aircraft nose direction; GNSS module heading must match FC orientation Interference Avoidance: GNSS and RTK modules should be positioned away from high-current devices, high-frequency EMI sources, or active antennas GPS Position Correction: DRACO supports precise GPS-based installation correction (1m with 0.01 resolution) Max Attitude Angle: Factory-configured to restrict unsafe pitch/roll during flight Model Summary Model Voltage Weight CAN Size (mm) Key Advantage DRACO D1 628S 159g 1 1006625 High-load UAVs, stable all-around control DRACO MINI2 614S 106g 1 744423 Built-in power, compact for light drones DRACO D3 628S 68g 1 674427 Lightweight, modular build flexibility DRACO SUPER4 1228S 180g 2 1066228 Flagship, Route 12 bus, advanced power F7 Open 628S 49g 2 734816 Open-source PX4, 16 PWM, multi-platform Applications Powerline inspection Surveying and mapping Agricultural spraying Emergency rescue VTOL systems Unmanned boats or ground vehicles Delivery and logistics UAVs
