The Flow breakout board is built around the Pixart PMW3901 optical flow tracking sensor and the ST VL53L0x ranging sensor and measures motion in 3 dimensions. We have used the same sensors in the Flow deck which is used by the Crazyflie drone for autonomous flight, but we thought that the functionality is so awesome that we developed the Flow breakout and made it compatible with Arduino to make it easy to use. With the Flow breakout it is possible create applications such as motion tracking of a robot, counting people entering a room or gesture tracking.
When you get your Flow breakout, follow the getting started guide to quickly get up and going by hooking it up to an Arduino and measure motion.
In the following weeks we are going to make a couple of Hackster project around the Flow breakout board so stay tuned for more motion tracking!
