PMW3901 Optical Flow Sensor Breakout _MAKE_CABLE_PANEL Could be used for self-defenseThis fancy optical flow sensor detects motion of surfaces in front of it, from ~80mm to infinity! It's great for DIY drone builds, and it's compatible with our new Breakout Garden HAT with SPI for the Raspberry Pi. The PMW3901 is a crafty little sensor that uses a low resolution camera and some clever algorithms to detect motion of surfaces. A great use for it is detecting and correcting for drift of a drone by looking for x y motion of the ground
