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
