AW9523B uses an I2C interface and allows using 4 expansion boards at the same time by modifying the i2c address and expanding up to 64 I/O ports.

• I2C bus allows expanding 16 I/O ports by just using two wires
• Support driving 16-ch common anode constant current LED, 256-step linear dimming, current controllable
• Output interrupt (INT) signal when changing the state of an input port
• I2C address configurable by shorting the A0/A1 jumpers
• Provides two connector options: PH2.0 header and/or solder pads, allows multi I2C modules to be stacked
