BreadBoarder-32U4 USB Arduino®-Leonardo Compatible Breakout-Prototyping Board


Arduino 1.01 and the Arduino Leonardo have been released! This is great news since the Leonardo bootloader and software feature set has now been clearly defined.

Here's your chance to experiment with the new Arduino "Leonardo" platform! The Leonardo uses the new USB-enabled ATmega 32U4 MCU, with a very powerful bootloader environment that emulates both a USB mouse and keyboard, as well as a virtual COM port!

The BreadBoarder series offers an Arduino-compatible breakout board for easy use with prototyping breadboards, or any other size-constrained application where the familiar Arduino board layout is helpful.

A key feature of the BreadBoarder is how the pinout of the headers matches* the standard Arduino board pinout, making it much more intuitive to work with compared to other breadboard solutions. (*the AREF connection has been moved to be next to the analog inputs, where it should have been all along!)

The boards supports power from both USB, and external (up to 15V) with diode-protected inputs, making stand-alone projects very easy to build.

Arduino 1.0 includes new commands for the Leonardo such as "Mouse.move(xReading, yReading, 0);" and "Keyboard.write(inChar);", which moves the mouse and types keyboard characters. Very neat for PC interface projects! (note that these new commands do nothing on the UNO, Duemilanove, or older Arduino boards...)

A 4-pin serial header is included that follows the pinout of commonly-available inexpensive ($15) Bluetooth transceiver breakout boards. All Cal-Eng boards feature this custom serial header pinout, making them all plug&play compatible with Bluetooth*.

* Bluetooth is an incredibly useful tool for wireless debugging and data tracking, and simply uses the Arduino serial monitor window. See our Bluetooth tutorial page for more info on these breakouts, and how they work.

As with most of our boards, we don't install or include headers or plugs, since the choice will vary greatly depending on the application and personal preferences.  They are available (at a very low cost!) in the "Wires, Headers & Plugs" category.  The 40-pin standard header would be the most common choice.
