1. How to connect the Radiolink 7P I2C expansion board to a PIXHAWK flight controller?
Plug the I2C cable from the Radiolink 7P I2C expansion board directly into the I2C port on your PIXHAWK or Mini Pix flight controller. Ensure the connector is aligned correctly to avoid damaging the pins or causing communication issues. This connection enables the drone expansion board for PIXHAWK to interface with multiple sensors using the I2C protocol. Secure the board with standoffs to prevent vibration-related disconnections.
2. How to use the I2C obstacle avoidance module for drone navigation?
Connect ultrasonic, ToF, or LiDAR sensors to the I2C obstacle avoidance module ports on the Radiolink 7P I2C expansion board for environmental sensing. Configure sensor parameters in Mission Planner or QGroundControl, enabling terrain hold, proximity limiting, or automated avoidance in flight modes like Loiter or Auto. The Mini Pix I2C expansion board streams real-time distance data to the flight controller for dynamic path adjustments. Always verify sensor alignment and field of view before flight.
3. How to add multiple sensors using the Mini Pix I2C expansion board?
The Mini Pix I2C expansion board provides seven I2C ports, allowing you to daisy-chain multiple sensors such as rangefinders, airspeed sensors, or GPS modules. Connect each device to an available port and ensure all have unique I2C addresses to prevent conflicts. This drone expansion board for PIXHAWK simplifies wiring and reduces clutter on the flight controller. Use the I2C scanner in Mission Planner to confirm all sensors are detected.
4. How to power the drone expansion board for PIXHAWK safely?
Power the Radiolink 7P I2C expansion board through the PIXHAWK’s I2C port, which supplies regulated 5V, or use an external 5V source with clean, stable output. Avoid connecting unregulated or noisy power, as voltage spikes can damage the I2C obstacle avoidance module or connected peripherals. If using an external BEC, ensure common grounding with the flight controller to maintain signal integrity.
5. How to troubleshoot connection issues with the Radiolink 7P I2C expansion board?
If sensors on the Radiolink 7P I2C expansion board are not detected, first verify cable integrity and secure connections at both ends. Use the I2C scanner tool in Mission Planner to check for live devices and identify missing or duplicated addresses. Ensure each I2C obstacle avoidance module or sensor is properly powered and configured for the correct I2C speed (100kHz or 400kHz). Reset the flight controller if the bus appears locked or unresponsive.
