How is the I2C address set?
The address ranges from 0x20 to 0x27 and is selected by tying the A0, A1 and A2 address pins high or low. Use this to put several expanders on the same bus.
Does it need pull-up resistors?
Yes. SDA and SCL need pull-up resistors to the supply, as with any I2C bus. Values around 4.7 kΩ are common for standard-speed buses, but confirm against your wiring length and bus speed.
