Hey guys!

I am looking to integrate the the PMW3901 Optical Flow Sensor Breakout Board with the latest Pixracer R15.

Here’s a link to the board:

This thing seems to be the smallest optical flow unit in the market.

Was wondering if anyone managed to get it working.

Seems that it will only communicate via SPI.
