Module with a 16-channel GPIO expander based on the AW9523B system. It allows you to extend the number of inputs and outputs of the microcontroller, as well as directly control the LEDs (with 256 levels of brightness) without the need to add a resistor. The expander will be perfect for connecting buttons, because it has the ability to generate an interrupt in the event of a change in input status. The module is powered with the voltage from 2.4 V to 5.5 V, and communication is via the I2C interface. Full documentation is available on the product page.
