16 Output I/O Expander Breakout - SX1509 heat shrink 3 V DatasheetThis is powerful 16 Output I O Expander Breakout based on chip SX1509 made by Semtech. What does it mean GPIO expander? It means that if you have only two pins signal (in your Arduino for example) you can use them as if they are 16 pin. The SX1509 module allows easy serial expansion of I O through I2C interface. SX1509 also can be used a fully programmable LED Driver with excellent lighting control such as intensity, blinking and fading, make them
