Description

SX1509 16CH I/O Output Module LED Driver Keyboard GPIO DIY for Arduino
Are you low on I/O? No problem! The CJMCU-SX1509 can use your I2C interface for 16 additional GPIO channels. And thats not all! This handy device also includes a fully programmable LED driver and a keypad scan engine that allows continuous keyboard monitoring of up to 64 keys! Since the I/O banks can operate between 1.2V and 3.6V (5.5V tolerant) independently of the core and from each other, this unit can also work as a level shifter.
This breakout board makes it easy to use prototypes with the SX1509, allowing you to add more I/O to your or I/O controller. Weve even created a library to get you started!
