Can you wire an ultrasonic sensor directly to an FPV flight controller

I’m building a large drone that will be used for something specific, and I need super stable flight and obstacle avoidance.

Hi there,

The Pixhawk 4 Flight Controller for example has analogue and I2C ports available, so you can connect an external Ultrasonic Sensor there. Here’s two quick examples I found on how to do this and there appear to be some videos on YouTube as well:

This is a great question! The Pixhawk 4 is such a versatile unit as suggested. I found the same as Liam, The PixHawk can handle Ultrasonic Sensors, however, I also found another great option for obstacle/ground level detection in a tiny LIDAR Sensor!

Incredible how compact these are. It’ll run on the PixHawk 4 connected via I2C or PWM.

Some great resources out there for it as well in combination with the PixHawk 4:
