The chip is an ATmega328 in DIP package, pre-loaded with the Arduino Optiboot (Uno 16MHz) Bootloader. This will allow you to use Arduino code in your custom embedded project without having to use an actual Arduino board.
The Digital Sandbox is equipped on board with everything you will need to complete 13 experiments, including controlling an LED, measuring how loud things are, detecting what the temperature is, and more.
The ITDB02 Series LCD module works in 3.3V voltage level and it's not compatible with Arduino MEGA pins , so we make a shield for Arduino MEGA. Now the user can directly plug the ITDB02 in the ITDB02 Arduino MEGA Shield and stand on the Arduino MEGA board.
