DollaTek 3Pcs PCF8574 I2C IO Expansion Board Module for MCU Projects

Product Overview

This pack includes 3 DollaTek PCF8574 I2C IO Expansion Boards, designed to extend the input/output capabilities of your microcontroller projects. Based on the efficient I2C interface, these modules allow you to significantly increase your available I/O pins, making them ideal for projects with limited MCU resources.

Key Features

• I2C Interface: Utilizes the I2C bus for communication, enabling easy integration and expansion.
• I/O Expansion: Expands 2 I/O pins to 8 additional I/O pins per module.
• Scalability: Supports cascading up to 8 PCF8574 modules simultaneously, potentially expanding to 64 I/O pins.
• Dual Interface Access: Offers two interface types for connection to your target board: Pin headers or row seats.
• I2C Bus Cascade: Allows for multiple I2C modules to be connected and used together.
