The Mega 2560 is a microcontroller board based on the Atmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs.
The Arduino ADK is a microcontroller board based on the ATmega2560 (datasheet). It has a USB host interface to connect with Android-based phones. It is compatible with Android’s Accessory Development Kit examples.
The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x) orATmega168 (Arduino Nano 2.x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package.
This transparent case is ideal for protecting your Arduino UNO microcontroller. It’s made from robust acrylic and held together with screws as opposed to plastic clips for maximum sturdiness.
The Arduino Uno R3 is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs.
The OV7660 camera module is a low-cost 0.3 megapixel CMOS color camera module, which is compatible with the OV7670 module that can output a 640×480 VGA resolution image at 30fps.
The ESP-8266EX-based Espressif development platform, almost compatible with the Arduino UNO pins, can also use some shield modules designed for the classic Arduino UNO.
