ButtonDuino: another "Smart Button" Arduino

Yes, small is better!
And after our Slenduino, we present a project of Ritesh Kanjee, a developer that has created a small version of arduino Attiny85 based.

Ritesh propose this solution on indiegogo.com, it's would be both low power and inexpensive arduino, with a USB programming included into the bootloader and compatible with most of future button shields.

<<We wanted the answer to the fundamental question, "How many students know how to program a microcontroller or have a basic understanding of electronics?">> right question!
We had answered to it with our Slenduino, but we are pleased that we aren't "the only one"!

Just for specifications:

• Atmel ATTINY85-20H microcontroller
• USB Regulated Powered up to 800mA via external power supply or 500mA from PC/Laptop.
• Dimensions: 18.64 mm x 18.25 mm (0.73in x 0.718in)
• Programmable via USB or AVR mkII - Choice between USB bootloader .
• Arduino IDE 1.0+ (Windows/OSX/Linux)
• 6 x Available I/O Pins and I2C and SPI Expandable
• 8k Flash Memory without bootloader ( 6k after USB bootloader)
• I2C and SPI Expandable
• 3 x 8 bit Hardware PWM  pins
• 4 x 10 bit ADC pins
• Power LED
• Test LED (Pin 1)
• Support for LabVIEW
• Soon to Be available in Deep RED (PCB Silkscreen)

Good project, you can find it on this indiegogo campaign page.
