Arduino Uno SMD Rev3 is a microcontroller board based on the ATmega328. 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 Uno differs from preceding boards in that it does not use the FTDI USB-to-serial driver chip.

Features of Arduino Uno SMD Rev3

The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform
It is a microcontroller board based on the ATmega328
Contains everything needed to support the microcontroller
14 digital input/output pins (of which 6 can be used as PWM outputs)
6 analog inputs
16 MHz crystal oscillator
USB connection
A power jack
ICSP header
A reset button
Differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip
Additional features of the R3 version are:
- ATmega16U2 instead 8U2 as USB-to-Serial converter
- Added SDA and SCL pins for TWI communication placed near to the AREF pin
- Two other new pins placed near to the Reset pin:
  - The IOREF that allow the shields to adapt to the voltage provided from the board
  - Second pin is a not connected, reserved for future purposes
- Stronger Reset circuit

Tinkerkit Dmx Master Shield

$12.95 $19.99

The TinkerKit! DMX Master Shield is used to drive a series of DMX receivers. In order to be programmed via Arduino, it requires the DMX Library Like a regular shield it has to be plugged on top of the Arduino and it can be stacked on top of other shields. It is used both as OUTPUT and INPUT (also if the official library at the moment supports only the OUTPUT communication). For each line it has two kinds of port that can be used: the DMX connector or normal pins. On the front it has two DMX connectors, one for the INPUT and one for the OUTPUT.
