	This item is OBSOLETE
ARDUINO Leonardo like board with ATMEGA32U4.
FEATURES
- ATMEGA32U4 microcontroller, all in one USB communication, no need for an external FTDI chip.
 - Input power supply taken from mini USB
 - Feeds power to the breadboard bus
 - Works on 3.3V
 - UEXT connector which allows many existing modules like RF, ZIGBEE, GSM, GPS to be connected
 - The LEDs and the BUTTONs are on the edge of the board so there is easy access even if the boards have shields on them
 - A Mini USB connector is used, which is common and used in most cell phones, so you do not have to buy other cables
 - Industrial grade -45+85C

FAQ
- I can't find compatible drivers in the latest 1.0.1 Arduino IDE/drivers folder. What should I do?
 - You have to program the board with the latest bootloader available.
 
- I installed version 1.0.0 of Arduino IDE but I can't find Leonardo under boards
 - Un-comment the Leonardo section in the "\hardware\arduino\boards.txt" file in your Arduino IDE install location
 
- I disabled all interrupts and entered an infinite loop code on my board and now the bootloader won't start. How do I start it?
 - You need a programmer to program the bootloader again. Avoid disabling interrupts at all costs.
