SX1509 16 Output I/O Expander Breakout
The CJMCU-SX1509 can tie 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 is sustained From 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 or I / O limited controller.
