PCF8575 Remote 16-Bits I2C IIC SMBus I/O Expander Module
The PCF8575 I/O Expander Module is based on PCF8575 Chip. The PCF8575 device provides general-purpose remote I/O expansion for most microcontroller families by way of the I2C interface [serial clock (SCL), serial data (SDA)]. The device features a 16-bit quasi-bidirectionalinput/output (I/O) port (P07–P00, P17–P10), including latched outputs with high-current drive capability for directly driving LEDs. Onboard 3.3V level converter circuit, if you don’t have a solder pad of VCC-VDD, the PCF8575 level is 3.3V. If you solder it, the level will be the same as with VCC.
