The SBUS pin is inverted and connected to RX6. Non-SBUS single-wire serial inputs can be tied directly to RX6 if the SBUS pin is left unconnected. You may also use other UART ports (e.g., UART2 / UART4 / UART8) for RC input by setting the serial protocol parameters in ArduPilot. OSD Support (ArduPilot) Supports OSD via OSD_TYPE 1 (MAX7456 driver) and OSD_TYPE 5 (MSP_DISPLAYPORT). VTX Support The SH1.0-6P connector supports O3 Air Unit / HD VTX connection. Protocol defaults to DisplayPort. Note: Pin 1 is 9V output — do not connect it to a 5V-only peripheral. PWM OutputThe FC supports up to 10 PWM outputs:Channels 1-10 support DShot.Channels 1-8 support bi-directional DShot.Note: PX4 & INAV do not currently support BDShot on this target.PWM outputs are grouped (each group must use the same protocol):Group 1: 1, 2, 3, 4Group 2: 5, 6Group 3: 7, 8, 9, 10Battery Monitoring The board includes an internal voltage sensor and supports an external current sensor input via the ESC connector. Voltage sensing supports up to 6S LiPo. Default ArduPilot battery parameters: BATT_VOLT_PIN: 10BATT_CURR_PIN: 11BATT_VOLT_MULT: 21.2BATT_CURR_SCALE: 40.2Compass Built-in compass sensor: IST8310. External compass can also be connected via I2C (SDA/SCL).

Wide Compatibility: Supports all major open-source flight control systems, including Ardupilot, PX4, and Betaflight, with official firmware support. INAV will be officially supported from version 8.0, ensuring your flight control system stays up-to-date with the latest technology. High-Precision Dual IMU Sensors: Equipped with dual IMU and an integrated compass, providing higher-quality IMU data for navigation tasks such as waypoint flying or hovering, significantly improving the accuracy of navigation and positioning in complex environments. O3 FPV Support: Specifically designed compatibility with the O3 Air Unit, supporting HD video transmission and providing a smooth first-person view (FPV) flying experience, meeting professional-grade FPV demands. Rich Expansion Interfaces: Features 7 UARTs, 10 PWM outputs, USB Type-C, and support for CAN and I2C buses, allowing connectivity to a variety of external devices such as onboard computers and optical flow laser sensors, offering extensive expandability. High-Performance MOSFET Devices ESC: The Electronic Speed Controller uses 40V 165A RDS=1.1mR MOSFET devices, which are key to enhancing ESC performance. An RDS(ON) as low as 1.1mR means minimal internal resistance during current flow, reducing energy loss, increasing efficiency, and resulting in lower heat generation and better load capacity. Especially during long periods of high load, this significantly lowers failure rates and extends lifespan. User-Friendly Design and Support: Features an all-connector design to reduce soldering work and improve connection reliability. Additionally, we offer detailed usage tutorials and continuously update settings and optimization guides for different firmware, helping users get started with ease.
