Features

*Classical Arduino controller board, reference version of later Arduino Boards. *Suitable for Arduino beginners.

*Atmel SAM3X8E-based (32-bit ARM microcontroller) Arduino controller board. Note：unlike other Arduino boards, DUE only supports 3.3V operating voltage, which could be not compatible with 5V shields and peripheral devices.

*Low-cost, more analog and digital ports than UNO, 2 UARTs. *For low-cost Arduino projects.

*54 digital ports, 16 analog ports, much more IO ports. *Applicable to large project scenarios that need more sensors.

*Atmega2560-based controller board, fully compatible with Google ADK. *For realizing USB data communication with Android mobile system.

*A microcontroller based on Atmega32U4 , pretty small size, compatible with small breadboards. *Suitable for projects with size requirement.

*A controller board based on ATmega32u4 and Atheros AR9331. Atheros supports Linux-based branch of OpenWRT platform Linino system. *Applicable to developers who want to build up Arduino-based IoT projects.
