Pixy2 is the second version of Pixy. It's faster, smaller and more capable than the original Pixy, adding line tracking/following algorithms as well as other features. 

Here's what we've added to Pixy2:

• Pixy2 detects lines, intersections and small barcodes, intended for line-following robots
  

• Improved framerate – 60 frames-per-second

• Tracking algorithms have been added to color-based object detection

• Improved and simplified libraries for Arduino, Raspberry Pi and other controllers

• Integrated light source

And of course, Pixy2 does everything that the original Pixy can do:

• Small, fast, easy-to-use, low-cost, readily-available vision system
  

• Learns to detect objects that you teach it

• Connects to Arduino with included cable. Also works with Raspberry Pi, BeagleBone and similar controllers

• All libraries for Arduino, Raspberry Pi, etc. are provided

• C/C++ and Python are supported

• Communicates via one of several interfaces: SPI, I2C, UART, USB or analog/digital output

• Configuration utility runs on Windows, MacOS and Linux

• All software/firmware is open-source GNU-licensed

• All hardware documentation including schematics, bill of materials, PCB layout, etc. are provided

Typical Functions Overview

• Seven color signatures

• Hundreds of objects

• Teach it the objects you’re interested in

• Pixy2"tracks"each object it detects

• color code

• Detecting and tracking lines

• Detecting Intersections and"branching"
