Features: Based on the I2C interface I / O expansion modules, using two I / O can be extended to eight I / O (up to simultaneous use 8 PCF8574. expanded to 64 I / O).

Maximum Features: supports two types of Interface, access to the target board: Pin or row seat.

2 supports I2C bus cascade (via pin, row seat docking methods can be used simultaneously multiple I2C modules).

Typical applications: for I / O resource constraints the MCU I / O expansion.

The main resources: PCF8574. I2C interface, the 8-bit parallel.
