The Arduino Leonardo is a microcontroller board based on the ATmega32u4 (datasheet). It has 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, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
The Arduino 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, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega 2560 board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila.
The Mega 2560 is an update to the Arduino Mega, which it replaces.

With this shield you can easily connect to a CAN (Controller Area Network) Bus. Discover new possibilities of interaction between your Arduino MKR Board and the CAN ecosystem.
The MKR CAN shield can simplify the connection of the MKR boards with industrial systems and especially with automotive applications. This shield opens a new set of possible applications like smart vehicles, autonomous cars and drones. A CAN connection also provides the possibility to connect a MKR board directly with several types of industrial grade sensors, motors and displays.
With the MKR VIDOR 4000 you can configure it the way you want; you can essentially create your own controller board. It comes loaded with hardware and potential: an 8 MB SRAM; a 2 MB QSPI Flash chip — 1 MB allocated for user applications; a Micro HDMI connector; an MIPI camera connector; and Wifi & BLE powered by U-BLOX NINA W10 Series. It also includes the classic MKR interface on which all pins are driven both by SAMD21 and FPGA. Plus, it has a Mini PCI Express connector with up to 25 user programmable pins.
The FPGA contains 16K Logic Elements, 504 KB of embedded RAM, and 56 18×18 bit HW multipliers for high-speed DSP. Each pin can toggle at over 150 MHz and can be configured for functions such as UARTs, (Q)SPI, high resolution/high frequency PWM, quadrature encoder, I2C, I2S, Sigma Delta DAC, etc.
The on-board FPGA can be also used for high-speed DSP operations for audio and video processing. This board also features a Microchip SAMD21. Communication between FPGA and the SAMD21 is seamless.
You can find in the Getting Started section all the information you need to configure your board, use the Arduino Software (IDE), and start tinker with coding and electronics.
The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328P (Arduino Nano 3.x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.
The Arduino Uno SMD 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, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
The Yún rev. 2 with the power of a Linux based system that enables advanced network connections and applications.
Connection to your WiFi or wired network is simple thanks to the Yún Web Panel and the dedicated ”YunFirstConfig” sketch. The Web panel allows you to manage your shield preferences and upload your sketch. The Yún rev. 2 uses the Bridge library and so extends the board capabilities by using the Linux processor.
As always, every element of the platform – hardware, software and documentation – is freely available and open-source. This means that you can learn exactly how it’s made and use its design as the starting point for your own projects.
