banana pi zbh. I2C GPIO extend board

Product Overview:
This module is designed specifically for expand for the GPIO of the Banana Pi a which can effectively solve the banana send IO port insufficient. It use PCF8574 chip to expand 8 Bidirectional IO. The module connection to the Banana Pi through I2C bus. There are 8 I2C address in the module and user can choose one of them through setup the ?ADDR? jumper. User also can choose 5V or 3.3V electric level. Module with isolation protection, can effectively prevent external high voltage damage to the Banana Pi. Multiple module can cascade.

Product Features:

  • 8 Bidirectional IO
  • 8 I2C-address
  • Isolation protection
  • Use wiringPi API , sample code
  • 100 kHz I2C-bus interface (Standard-mode I2C-bus)



  • Banana Pi insert port
  • Banana Pi cascade port
  • EXT0-EXT7 expand GPIO
  • Electric level selection jumper
  • I2C-address selection jumper

Product Parameters:

  • Working voltage: 2.5V-6V
  • IO voltage: 3.3V or 5.5
  • Expand 8 Bidirectional IO
  • I2C bus
  • 100 kHz I2C-bus interface (Standard-mode I2C-bus)
  • -40°C to +85°C operation


Typical Application:

  • LED signs and displays
  • Key pads
