IIC GPIO Module CT8314 Convert 16 Digital IO Ports Read-Write 8 Simultaneous Parallel Modules For Arduino

When usIing Arduino to make robots or perform interactive media, have you found digital IO ports are not efficient? Arduino UNO and Leonardo often face this problem. How can we make use of existing resources to expand sufficient Arduino ports? Actually, we are able to solve this problem through the Arduino I2C IC GPIO Module which can achieve communication through Arduino two IIC data lines (SDA / SCL), thus converting the readable and writable 16 channel digital I / O port.
In addition, 8 modules can be in parallel simultaneously , and each module can be set to different IIC address, through which you could parallel multiple modules for data acquisition and control according to the demand of project digital ports. A total of 128 digital ports are spared, double of MEGA2560. If you cant use I2C,SPI or other protocols, it is necessary to equip with an expanded version of IO.
