SX1509 16 csatornás I / O kimeneti modul és billentyűzet GPIO feszültségszint LED meghajtó

SX1509 16 Channel I/O Output Module And keyboard GPIO Voltage Level LED Driver
DescriptionThe 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 InterfacePackage include:1 x SX1509 16 channel I/O output module and keyboard GPIO vo
