Product description: I2C GPIO pinout expander and LED driver - AW9523 - STEMMA AT/Qwiic - Adafruit 4886
GPIO pin expanderand LEDdriver. Equipped withAW9523chip, provides up to16 additional GPIO inputs / outputs. Uses I2C bus to communicate with connected elements. As many as four expanders can be connected, due to four I2C addresses available. Allows control ofLEDsin the range of256lineardimming. Poweredfrom2.5V to 5.5V.
Product compatible with Arduino and Raspberry Pi.
A detaileduser guideis available on the manufacturer's website, which includes connection diagrams to individual controllers and libraries forArduino IDEandPythonenvironments.

Pinouts description
Module is equipped with leads in form ofsoldering fields, to which you should attachgoldpinconnectors, included in set. Alternatively, the element is also equipped withSTEMMA QT / Qwiicconnectors, through which it is possible to conveniently connect the module with the controller board - without additional soldering.
