The Flow breakout board is used for motion tracking and can easily be connected to any robotics project or other design.
The motion of a surface, usually the ground, is measured and is reported as delta X and delta Y by the optical flow sensor. The absolute distance (Z) is measured by the Time of Flight ranging sensor. It comes with an Arduino library to easily read the movement data and has a large voltage range for IO and power supply.
The Flow breakout features the VL53L0x ToF sensor and the PMW3901 optical flow sensor.
Features
Fast, accurate distance ranging
Measures absolute range up to 2m
Measures movement in X/Y using optical sensor
Power supply and IO 3V - 5V compatible
Arduino library for easy usage
Minimum range for motion tracking is 80mm
VL53L0 ranging sensor
The VL53L0 ranging sensor is facing front on the board. It is accessible on the I2C pins SCL and SDA.
PMW3901 optical flow sensor
The PMW3901 optical flow sensor is facing front on the board. Is is accessible on the SPI pins CS, MISO, MOSI, CLK. The pins MOTION and /RESET are also connected to the PMW3901. The reset pin can be left floating if not needed.
The optical flow sensor will output motion count. Assuming the board is moving above a flat surface the X/Y orientation is as follow:
Arduino drivers
You can install Arduino libraries using the Arduino library manager.
The VL53L0x has been succesfully tested with the following drivers:
