PCF8575 Remote 16 Bits I2C IIC SMBus I/O Expander Module

PCF8575 Remote 16 Bits I2C IIC SMBus I/O Expander Module

PCF 8575 IO Expander Module I2C To 16 IO

Are the I/O pins exhausted? This PCF8575 Remote 16 Bits I2C IIC SMBus I/O Expander Module is a large module allows the user to expand up to 16 i/o with only two i/o for control. The PCF8575 is connected via an I2C interface and features 16-bit near-bi-directional input/output pins.
