Adafruit pin expander equipped with PCF8575 chip. It has as many as 16 pins of GPIO inputs/outputs, thanks to which increases the design possibilities of the modules used. It communicates using the I2C bus, has 3 configurable interface addresses. On the board, there are two STEMMA QT / Qwiic connectors and soldering pads to which the goldpin strip included in the set should be soldered.
Main features:
- Multiple I/O mode - thanks to 3 address pins, you can get up to 8 outputs on one bus, which gives a total of 8 x 16 = 128 GPIOs on one I2C bus
- The module can be programmed using Arduino and CircuitPython - the manufacturer provides libraries and sample program codes
- The board has STEMMA QT / Qwiic connectors that allow for quick prototyping of systems without the need to solder the connector
