## Description

The "Eleven" is just like an Arduino Uno – but better!

It is based on the existing Arduino Uno but with improvements and updates for ease of use, cost and getting started, so it's 100% Arduino compatible. Also included in the package are a USB cable, and our Getting Started guide sheet.

As well as the standard Arduino Uno features found here, the Eleven has the following improvements and updates:

**Prototyping area**
 For those projects where you don't need the extra size or expense of a shield, the Eleven has its own standard prototyping area taking up a quarter of the board. Great for quick sensor and IC projects. There's extra power pads underneath for neat connections.

**LEDs visible on the edge**
 Wondered what your Arduino was doing? We've carefully placed a nice blue Power LED, plus colour coded RX, TX and D13 LEDs on the right edge of the board so you can see what's going on.

**Dual crystals**
 We've provided proper crystals for both the primary MCU and the communications MCU, rather than using a ceramic resonator.

**Micro-USB Connector**
 No more short circuits of the large USB connector against your shields. Our standard Micro-USB connector is firmly mounted and we've included a cable too. Better still, it allows you to power your Eleven from most cellphone chargers!

**Overlay guide where you need it**
 When you're soldering your project, it's good to know what you're connecting to! All of our boards and shields have a thorough pinout and guide printed on the bottom as well as the top, so when you're soldering underneath there's no need to flip the board over constantly.

**Top spec MCU**
 Every Eleven has the top specification ATmega328P Microcontroller.

**D13 pin works for everything**
 The digital I/O pin 13 functionality has been fixed, the D13 indicator LED no longer loads up this pin when you use it as an input.

**Mounting holes and power jack**
 We've included a fourth mounting hole in the bottom left, there's no more wobbly board troubles if you're fitting it to a case.
 Helpful markings for the Power Jack size, polarity and voltage are right there on the board when you need them. Auto-power switching and self-resetting fuse protection are standard.

**It's all in the same place**
 The power jack, headers and ICSP are all in exactly the same location as Arduino standard boards. The Eleven is perfectly compatible with all Arduino shields, projects and sketches.
