This is our lower cost alternative to the standard R3 Uno, but in this case lower cost doesn't mean less features. In fact we have made several improvements to the standard R3 Uno, hence the 'plus'. By taking advantage of the latest USB components together with using surface mount technology for the main processor we have been able to significantly reduce the cost of this development board. But what's the plus all about? Well, whilst making changes to the latest R3 design we also decided to add a few improvements:
The first thing you may notice is the additional header pins supplied with the board. These can be fitted to the row of headers that we have added alongside the standard Arduino headers giving it more connect-ability. Add them to the upper side of the board to have additional connections to each pin, or add them to the bottom to get access to pins obscured by shields.
We also know that when experimenting you can never have enough power connections so we've added a header with plenty of 5V, 3.3V and GND pins. Plus added pins for Serial and I2C interfaces.
We've even improved on the standard artwork to make it clearer, and on the underside we've also added extra information for alternative pin functions - very useful if you like to hack your Uno.
We've changed the USB interface to lower the cost of the board.
But don't worry, despite all the improvements it's still an Uno. It will work just as well with the Arduino IDE and is compatible with any hardware that works with an ordinary R3 Uno.
Just install the drivers (links available on our support forum here) and select the board type as 'Arduino Uno' and you're good to go.
