The CAT9555 IO Expansion Module specifically provides 16−bit parallel input/output port expansion for I2C and SMBus compatible applications.
These I/O expanders provide a simple solution in applications where additional I/Os are needed: sensors, power switches, LEDs, buttons, and fans.
In order to be convenient for users, we provide the demo codes based on Raspberry Pi, Ardui. UNO and STM32.
