Arduino IIC I2C TWI GPIO Module to 16CH Digital Input Output IO Port Module for DIY
Description:
IIC TO GPIO module is mainly to solve the problem of insufficient motherboard IO port, as long as 1 channel IIC on the main board is available, using this module for extension, you can extend the 16 channel digital IO port, read and write. Can be paralleled with 8 modules, each module can be set address.
For example, when making robot with Arduino UNO or interactive media, we can use 2 data lines (SCL-Analog PIN 5, SDA-Anlog PIN4) and make IIC I/O module communications, will be converted to 16 digital IO port, read and write. Can control more electronic building blocks.
GPIO IIC module can be achieved through the Arduino two IIC data line (SCL / SDA) to achieve communication module, you can read and write 16 channel digital I/O port. In addition, the 8 modules are available at the same time, each module can be set up to different IIC addresses, through which you can be parallel data acquisition and control of multiple modules based on the project requirements of the digital port.
Connect: vcc-5v gnd-gnd sda-a4 scl-a5 (I/O int interrupt interface) A0, A1, and A2 set different IIC addresses when parallel (0x20-0x27) with other modules.
Working voltage: DC voltage
Parameters:
- Module power supply: +5V
- 16 digital IO mouth comes with internal pull
- Can set 8 address (address range 0x20 ~ 0x27)
- Can be parallel to the 8 modules (IIC bus need to add)
- Module size: 42x40mm
Package included:
- 1 x Module
