The Arduino Funnel I/O (Fio) is a board designed by Shigeru Kobayashi, based on the original design from LilyPad.
Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free...
The Arduino Mini is a small microcontroller board intended for use on breadboards and when space is at a premiumand. The revision 05 has a new package for the ATmega328 (datasheet), which enables all components to be on the top of the board.
This is the Arduino Uno R3, mother of all duino's. The most used board in the family. Starting with arduino, this is your board!
The Arduino USB Host Shield allows you to connect an USB device to your Arduino board. The Arduino USB Host Shield is based on the MAX3421E (datasheet), which is an USB peripheral/host controller contains the digital logic and analog circuitry necessary to implement a full-speed USB peripheral or a full-/low-speed host compliant to USB specification rev 2.0.
ATMega328 32K microcontroller with pre-loaded Arduino Uno bootloader
The Genuino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 14 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.
