Arduino Boards

Arduino Uno

The Arduino Uno is an Arduino with the through-hole ATmega328, and is the next step in the evolution of the original form factor. It was the first to use the Atmel ATmegaxU2 instead of an FTDI USB to Serial chip. It was also the first of the Arduino format boards to use a ceramic resonator instead of a crystal.

Arduino Due

The Arduino Due is the first Arduino to use a non-ATmega chip, although the ATSAM3X8E is an Atmel made Arm Cortex M3. The MCU runs at 84MHz. It is pin-compatible with the Arduino Mega boards, but is 3.3V only. Only 3.3V shields will work. 5V shields will probably damage the board.

Arduino Esplora

The Arduino Esplora is a microcontroller board derived from the Arduino Leonardo. The Esplora differs from all preceding Arduino boards in that it provides a number of built-in sensors for interaction. It is designed for people who want to get up and running with Arduino without having to learn about the electronics first.

Arduino Leonardo

The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

Arduino Micro

The Micro is similar to the Arduino Leonardo in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

Arduino Robot

The Arduino Robot is the first official Arduino on wheels. The robot has two processors, one on each of its two boards. The Motor Board controls the motors, and the Control Board reads sensors and decides how to operate. Each of the boards is a full Arduino board programmable using the Arduino IDE.

Arduino Yún

The Arduino Yún is a microcontroller board based on the ATmega32u4 (datasheet) and the Atheros AR9331. The Atheros processor supports a Linux distribution based on OpenWRT named Linino. The board has built-in Ethernet and WiFi support, a USB-A port, micro-SD card slot, 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a 3 reset buttons.
