NEW GUIDE: Adafruit AW9523 GPIO Expander and LED Driver #AdafruitLearningSystem #Adafruit @adafruit
A cute and powerful I2C expander with a lot of tricks up it’s sleeve!
Expand your project possibilities, with the Adafruit AW9523 GPIO Expander and LED Driver Breakout – a cute and powerful I2C expander with a lot of tricks up it’s sleeve. GPIO expanders work like this: you have a board with some number of GPIO but not enough for your project – maybe you need more buttons or LEDs. Connect this board over I2C and then you can send/receive I2C commands to control the GPIO pins to write and read them.
The new Adafruit AW9523 GPIO Expander and LED Driver guide has everything you need to get started with your board. There’s an overview, a pinouts page, and resource downloads available. There’s also info on how to get started using it with CircuitPython and Arduino, including wiring diagrams and code examples.
