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.

SELECTION GUIDE
The landscape of K–12 education is rapidly evolving, moving from simple digital making to complex problem-solving with Artificial Intelligence. At DFRobot, we believe in equipping educators with the best tools and knowledge to navigate this shift. That is why we are thrilled to announce that DFRobot will be a featured presenter at the upcoming 2026 Fab Educators Summit on Friday, January 30th.
NEWS
From smart wearables and robotic skins to industrial monitoring, Force Sensitive Resistors (FSR) and Thin Film Pressure Sensors are essential components for tactile feedback. DFRobot offers a comprehensive range of force sensors, but choosing the right one can be tricky.
