DEVMO 5PCS PCF8574 I2C Interface 8bit IO MCU Expansion Board I/O Expander IIC Bus Evaluation Development Module Compatible with AVR STM8 C8051F Ar-duino

Brand: DEVMO

Features:

• Electronics/Computers/Accessories/Computer Components/Single Board Computers
• The PCF8574 IO Expansion Board provides general-purpose remote I O expansion via the two-wire bidirectional I2C-bus (serial clock (SCL), serial data (SDA)).
• Based on the I2C interface expansion modules, using I O can expand I O (up to simultaneous use PCF8574, expanded to 64 O).
• Support two interface types access target board: Pin or row seat.
• This 8-bit input output (I O) expander for the two-line bidirectional bus (I2C) is designed for 2.5-V to 6-V VCC operation.

Details: As the I/O interface resources of MCU is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C expansion board, you can easily implement functions that require many I / O interfaces. It is fantastic for MCU based project.
