مميزات خاصة

  • 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.

وصف

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.
