  • PCF8574T Breakout Board
Description

The PCF8574T Breakout Board is a practical and efficient solution for expanding the input/output capabilities of your microcontroller. Featuring the PCF8574T I/O expander chip, this breakout board provides 8 additional I/O pins through an I²C interface, making it ideal for projects that require more I/O pins than your microcontroller can provide.

8 Additional I/O Pins
Expands your microcontroller's I/O capacity by providing 8 extra pins.

I²C Interface
Utilizes a simple two-wire I²C interface for communication, requiring only two pins from your microcontroller.

Configurable Addresses
Supports up to 8 different I²C addresses, allowing multiple PCF8574T boards to be used simultaneously.

Bidirectional I/O
Each of the 8 I/O pins can be configured as either input or output.

Low Power Consumption
Designed for energy-efficient operation, suitable for battery-powered applications.
