SX1509 16 Output I/O Expander Breakout

Description: The SX1509 is an ultra low voltage General Purpose parallel Input/Output (GPIO) expander. It allows easy expansion of 16 extra channels of GPIO through a standard 400kHz I2C interface. This device contains an on-chip keypad scanning engine which enables continuous keypad monitoring of up to 64 keys! In addition, the board also features a fully programmable LED driver with internal oscillator for enhanced lighting control. Since the I/O banks can operate between 1.2V and 3.6V (5.5V tolerant) independent of both the core and each other, you can also use this device as a level-shifter.

This breakout board makes it easy to prototype using the SX1509 so you can add more I/O onto your I/O limited controller or Arduino. This Arduino Library should help you get started!
