Raspberry Pi 2 Model B RPI B I2C GPIO Expansion Board IO Extend Module RPI B
Description:
This module is designed specifically for expand for the GPIO of the Raspberry Pi a which can effectively solve the Raspberry 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 Raspberry 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)
Port:
- Raspberry Pi insert port
- Raspberry 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)
- Operation tem.: 40 C to +85 C
Typical Application:
- LED signs and displays
- Key pads
- Instrumentation and test measurement
- Driver numeric display
- Drive the lattice screen
How to use:
Insert the module that the silk screen says RPI IN Pay attention dont make the direction reversed! The correct direction of insert module is above the Raspberry Pi s PCB; EXT0-EXT7 are expand GPIO,user can use DuPont Line to connection peripheral. The header which near silk screen write EXT expand GPIO of Raspberry Pi, user can cascade the other module or the same module. If you want switch the electric level, just setup the jumper
Package included:
- 1 x Raspberry Pi 2 Model B RPI B I2C GPIO Expansion Board
