<p><table>

<tr><th>CPU</th><th>Known breakout board(s)</th></tr>
|
|
<tr><td>ATmega32U4</td><td><a href=http://www.pjrc.com/store/teensy.html>Teensy 2.0</a>, <a href=http://www.adafruit.com/products/296>Adafruit Atmega32u4 Breakout Board</a></td></tr>

<p>Make sure you pick the right .hex file for your dev board!</p>

|
<p>ATmega32U4 breakout boards are usually the best choice, on a price basis.</p>
|
|
|
|
<p>AT90USB1286 boards work equally as well, and have more memory (which can be essential if you want to set up a <i>very</i> large number of layers and/or macros), but cost more.</p>
|
|
|
|
<p><i>Note: the ATmega16U4 build is very close to 16KB in size, and probably does not leave room for a USB bootloader on the chip.<br/>
|
|
So, ATmega16U4 based breakout boards are not recommended for novices!</i></p>

The Teensy family have the PJRC bootloader installed and are programmed using <a href="http://www.pjrc.com/teensy/loader.html">PJRC's Teensy Loader</a>, available for all common OS.
|
|
</p>
|
|
<p>
|
|
Other breakout boards usually have the Atmel DFU bootloader installed and can be programmed using <a href="http://www.atmel.com/tools/FLIP.aspx">FLIP</a>.<br/>
|
|
FLIP is available for Windows and Linux. For Mac OS-X, see this <a href="http://www.pensieridigitali.com/2010/10/24/upgrade-psgroove-ps3break-with-mac-osx-at90usb162/?lang=en">guide on how use DFU-programmer</a>.

Arduino Leonardo can be programmed using <a href="http://www.nongnu.org/avrdude/">avrdude</a>, or the Arduino IDE.
