Specification:

• Function Description: I2C-based interface I/O expansion module, the use of two I/O can be expanded to 8 I/O (more than 8 PCF8574 can be used simultaneously, expanding to 64 I/O)
• Features: Support for two types of interfaces to access the target board: a row of pins or a row of sockets
• Features: Support I2C bus cascade (through the row of pins, row of sockets docking method, you can use more than one I2C module at the same time)
• Typical applications: I/O expansion for MCUs with scarce I/O resources
