Overview and Specifications:

This Easy IO Expansion Shield is compatible for Arduino UNO / Leonardo / Mega2560. It is a connection bridge between the electronic building block module and board for Arduino.

It extends SPI port, UART, I2C, PWM and analog INPUT pins for Arduino board, so DIY enthusiasts, interactive designers can quickly attach the modules to the board for Arduino and accelerate project development progress.

Easy to plug OPEN-SMART products with XH socket to this shield and do not need to pay attention to the connection. So it is great for Training institutions and visual programming education
