SX1509 16 Channel I/O Output Module & keyboard GPIO Voltage Level LED Driver

Description：

The SX1509 can leverage your I2C interface for 16 extra channels of GPIO. And that’s not all! This handy device also contains a fully programmable LED driver and a keypad scanning engine which enables continuous keypad monitoring of up to 64 keys! Since the I/O banks can operate between 1.2V and 3.6V (5.5V tolerant) independent of both the core and each other, this device can also work as a level-shifter.

This breakout board makes it easy to prototype using the SX1509 so you can add more I/O onto your Arduino or I/O limited controller. We’ve even spun up an Arduino Library to get you started!

Features:

Enable Direct Level Shifting Between I/O Banks and Host Controller
5.5V Tolerant I/Os, Up to 15mA Output Sink on All I/Os
Integrated LED Driver with Intensity Control
On-Chip Keypad Scanning Engine Supports Up to 8x8 Matrix (64 Keys)
16 Channels of True Bi-directional Style I/O
400kHz I2C Compatible Slave Interface

Package include:

1 x SX1509 16 channel I/O output module and keyboard GPIO voltage level LED driver
