AVR-T32U4  

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
