The SX1509 Breakout is a 16-channel GPIO expander with an I2C interface – that means with just two wires, your microcontroller can interface with 16 fully configurable digital input/output pins. The SX1509 can also produce PWM signals, dim LEDs. It can be set to blink or even breathe pins at varying rates. And, with a built-in keypad engine, it can interface with up to 64 buttons set up in an 8x8 matrix.
