Description
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.

[Wiki]Flow breakout board
The flow breakout board contains a VL53L0x ranging sensor as well as a PMW3901 optical flow sensor. It is the breakout version of the Crazyflie 2.0 Flow deck.
Getting started with Flow breakout board
This getting started will walk you through the process of getting sensor values from the Flow breakout board using an Arduino UNO. The process should be applicable to any arduino-compatible board that has I2C and SPI support.
描述
流量分析板用於運動跟踪，可以輕鬆連接到任何機器人項目或其他設計。
測量表面（通常為地面）的運動，並通過光學流量傳感器報告為ΔX和ΔY。絕對距離（Z）由飛行時間測距傳感器測量。它配備了一個Arduino庫，可輕鬆讀取移動數據，並具有用於IO和電源的大電壓範圍。
Flow Breakout具有VL53L0x ToF傳感器和PMW3901光學流量傳感器。
