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

The PCF8575 is a versatile 16-bit I/O expander module that communicates over the I2C or SMBus interface. It allows microcontrollers with limited GPIO pins to expand their I/O capabilities significantly by adding 16 extra digital input/output pins. This makes it ideal for applications such as keypads, sensors, LEDs, relays, and other digital peripherals. The module supports multiple address configurations, allowing up to eight devices to operate on the same bus. Its efficient design and low power consumption make it suitable for embedded and IoT applications.Features of PCF8575 Remote 16 Bits I2C IIC SMBus I/O Expander Module:Based on the PCF8575 I/O expander chipProvides 16-bit parallel I/O expansion for microcontrollers via I2CCompatible with standard I2C and SMBus interfacesUp to 8 modules can be connected using different I2C addressesEach I/O can be independently configured as input or outputLow power consumptionSuitable for controlling LEDs, switches, and other digital devicesCompatible with Arduino, Raspberry Pi, ESP32, STM32, and other platformsSpecifications of PCF8575 Remote 16 Bits I2C IIC SMBus I/O Expander Module:Operating Voltage: 2.5V to 5.5VCommunication Interface: I2C / SMBusI2C Address: Configurable using A0, A1, A2 pins (up to 8 addresses)I/O Channels: 16 (P00 to P15)Output Type: Open-drainMounting: Header pinsPackage Includes:1 x PCF8575 Remote 16 Bits I2C IIC SMBus I/O Expander Module
