- The PCF8574P is an 8-bit remote I / O expander for the I2C bus with 16-pin DIP packet interrupt. - Provides general-purpose remote I / O expansion via a two-wire, two-way I2C bus (Serial Clock (SCL), Serial Data (SDA)).
- Devices consist of eight quasi-directional ports , 100KHz I2C bus interface, three hardware address inputs and interrupt output operating between 2.5V and 6V.
- Quasi-bidirectional port can be independently assigned as one input to monitor interrupt status or keyboards or as an output to activate indicating devices like LEDs. - System Master can read from the input port or write to the output port through a single register.

The INA219 breakout board can be powered by the 5V or 3V pin on your Arduino and communicates via I2C. If you want to sense an Direct Current (DC) with high accuracy and voltage too, we suggest you to use this sensor. I2C sensor can easily interfaced with arduino. It uses 4 pins only.
