PCF8574T I2C I/O Extension Board
PCF8574T I2C I/O extension board for expanding 8 digital I/O pins on Arduino, ESP32, and Raspberry Pi projects.
The PCF8574T I2C I/O Extension Board is a versatile module that expands the number of digital input/output pins for microcontrollers using the I²C interface. Based on the PCF8574T I/O expander IC, it provides 8 additional I/O pins with easy serial communication, allowing seamless integration with Arduino, ESP32, ESP8266, Raspberry Pi, and STM32.
This board is ideal for projects that require multiple buttons, LEDs, relays, or sensors, without using extra GPIO pins on the main microcontroller. It supports simple wiring, flexible addressing, and multiple devices on the same I²C bus, making it perfect for DIY electronics, robotics, home automation, and embedded applications.
