Arduino - Official Hardware

Official Hardware

The original Arduino hardware is manufactured by the Italian company Smart Projects. Some Arduino-branded boards have been designed by the American company SparkFun Electronics.

Fifteen versions of the Arduino hardware have been commercially produced to date:

1. The Serial Arduino, programmed with a DE-9 serial connection and using an ATmega8
2. The Arduino Extreme, with a USB interface for programming and using an ATmega8
3. The Arduino Mini, a miniature version of the Arduino using a surface-mounted ATmega168
4. The Arduino Nano, an even smaller, USB powered version of the Arduino using a surface-mounted ATmega168 (ATmega328 for newer version)
5. The LilyPad Arduino, a minimalist design for wearable application using a surface-mounted ATmega168
6. The Arduino NG, with a USB interface for programming and using an ATmega8
7. The Arduino NG plus, with a USB interface for programming and using an ATmega168
8. The Arduino Bluetooth, with a Bluetooth interface for programming using an ATmega168
9. The Arduino Diecimila, with a USB interface and utilizes an ATmega168 in a DIL28 package (pictured)
10. The Arduino Duemilanove ("2009"), using the ATmega168 (ATmega328 for newer version) and powered via USB/DC power, switching automatically
11. The Arduino Mega, using a surface-mounted ATmega1280 for additional I/O and memory.
12. The Arduino Uno, uses the same ATmega328 as late-model Duemilanove, but whereas the Duemilanove used an FTDI chipset for USB, the Uno uses an ATmega8U2 programmed as a serial converter.
13. The Arduino Mega2560, uses a surface-mounted ATmega2560, bringing the total memory to 256 kB. It also incorporates the new ATmega8U2 (ATmega16U2 in revision 3) USB chipset.
14. The Arduino Leonardo, with an ATmega32U4 chip that eliminates the need for USB connection and can be used as a virtual keyboard or mouse. It was released at the Maker Faire Bay Area 2012.
15. The Arduino Esplora, resembling a video game controller, with a joystick and built-in sensors for sound, light, temperature, and acceleration.
