Value Arduino Uno Compatible Board with USB Cable
Need an Arduino compatible board and want to save money? Then order these value boards from PMD Way.
They have the same ATmega328 microcontroller, same pinouts and use the same IDE as the original R3 - however are cheaper thanks to using the CH340 USB interface IC (instead of FTDI or ATmega) and the surface-mount microcontroller.
However you're not losing any functionality - plus a USB cable AND an inline header pin row is included. You can solder the pins into the useful holes that run in parallell with the stacking header sockets.
Like the Duemilanove, it not only has an expanded shield header with a 3.3V reference and a RESET pin (which solves the problem of how to get to the RESET pin in a shield) AND a 500mA fuse to protect your computer's USB port, but ALSO an automatic circuit to select USB or DC power without a jumper! The Uno is pin and code-compatible with the Duemilanove, Diecimilla and older Arduinos so all your shields, libraries, code will still work. The new R3 (3rd revision) of the UNO has a few minor updates, with an upgrade to the USB interface chip and additional breakouts for the i2c pins and an IORef pin.
Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.
Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing). Arduino projects can be stand-alone or they can communicate with software on running on a computer (e.g. Flash, Processing, Max/MSP).
