The CJMCU-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.

Package includes:

1 x SX1509 16 Output I/O Expander Breakout
