Note: The TwentyTen has now been superseded by the Eleven, which combines all the good features of the TwentyTen with an ATmega8u2 communications co-processor just like on the Arduino Uno. This page is left here for reference only, and it will not be produced again.
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 our 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.
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.
No more short circuits of the large USB connector against your shields, our standard Mini-USB connector is firmly mounted and we've included a cable too.
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 TwentyTen has the higher 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.
RX pin biased
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.
Mounting holes, power and X3 pads
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.
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.
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 TwentyTen is perfectly compatible with all Arduino Duemilanove shields, projects and sketches.
