The PCF8574 IO Expansion Board features I2C pinheader on one side, and I2C connector on the opposite side. Hence, it’s more flexible to connect the board to your development system. The board also supports I2C cascading, allowing the use of multi module connected to the I2C bus at the same time by connecting the pinheader and connector

Features:

• This is the I/O extended module used for I2C interface, you can use two of these modules to extend 8 I/O. 
  
• Supports Arduino cascading, and you can use at most 8 modules to extend 64 I/O at the same time. 
  
• Can be changed the address by set toggle switch. 
  
• PCB Size: 36 x 16mm/1.41*0.62". 
  
• Every 2 seconds, make P0-P7 port output High level, Low level, and put 3 toggle switches to ON, the address of module is 0x27.
