You need to hook up: - Vcc (either 5V or 3V3) and GND. - A0/A1/A2 each to either Vcc or GND for selecting the I2C address. - SCL/SDA to the respective pins on one of the IOIO I2C (TWI) buses. Pull-up resistor on each of these lines to Vcc. Resistance anywhere between 2.2k-10k should be fine. - Outputs (H/L/W) as per your application requirements.
