I2C Expansion Board

CrossFlight/PIXHAWK/Mini Pix/TURBO PiX

I2C Port Extension

Work with SUI04, Overall Synchronous Obstacle Avoidance

With maximum 6 ultrasonic sensors SUI04 connected to the expansion board, aircraft can avoid obstacles from 5 directions (forward/backward/left/right/upward) and altitude hold downward.

I2C Expansion Board

Expansion of I2C Port

If connect the I2C expansion board directly to the I2C/GPS port of Flight Controller, only ultrasonic sensors SUI04 can be affixed as the GPS port is occupied. If GPS and ultrasonic sensors need to be connected as the same time, a transfer board is essential to connect with the GPS/I2C port of flight controller first, then connect expansion board to the transfer board.

* I2C Expansion Board：I2C port of flight controller can be extended to maximum six.
