The TwentyTen from Freetronics is 100% compatible with the Arduino Duemilanove and associated shields and includes host of improvements making this the Arduino board of choice for 2010. The many enhancements include a prototyping area, LEDs where you can see them, extra mounting holes, higher spec ATmega328P and more...
Our Code: MCU-60040
The TwentyTen (“Duemiladieci”) is just like an Arduino Duemilanove – but better!
It is based on the existing Arduino Duemilanove but with improvements and updates for ease of use, cost and getting started.
It's 100% Arduino compatible. Also included in the package are a USB cable, and a Getting Started guide sheet.
As well as the standard Arduino Duemilanove features found here, the TwentyTen has the following improvements and updates:
For those projects where you don't need the extra size or expense of a shield, the TwentyTen 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.
Wondered what your Arduino was doing? Freetronics have 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.
No more short circuits of the large USB connector against your shields, the standard Mini-USB connector is firmly mounted and a cable is included.
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.
Every TwentyTen has the higher specification ATmega328P Microcontroller.
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.
The issue with an Arduino sometimes not booting in noisy environments has been corrected, the RX pin is now biased to prevent the bootloader freezing if it gets electrical noise on startup.
There's a new 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.
Really need to program the bootloader into an MCU? Not usually required, but we've included a DIP socket and the X3 programming pads for it.
The power jack, headers and ICSP are all in exactly the same location as Arduino standard boards. The TwentyTen is perfectly compatible with all Arduino Duemilanove shields, projects and sketches.
A Mini-USB cable so you don't need to purchase one separately!
