SX1509 16 channel IO Output Module
Do you need more I/O? Don’t worry! The CJMCU-SX1509 has you covered with 16 additional GPIO channels accessible through your I2C interface. But wait, there’s more! SX1509 16 channel IO Output Module also features a programmable LED driver and a keypad scanning engine that can continuously monitor up to 64 keys. Plus, its I/O banks can operate independently at a range of 1.2V to 3.6V (with 5.5V tolerance), making it suitable as a level-shifter for various systems.
The breakout board for the SX1509 simplifies prototyping by allowing you to expand the I/O capabilities of your controller, whether it is limited or not. Additionally, we have developed a Library specifically for this purpose to help you get started quickly.
