Digispark USB Development Board

The Digispark is an Attiny85 based microcontroller development board similar to the line, only cheaper, smaller, and a bit less powerful. With a whole host of shields to extend its functionality and the ability to use the familiar Arduino IDE the Digispark is a great way . Jump to INTO Electronics, or the when Perfect for the Arduino AN IS TOO Big TOO much or at The Digispark IS shipped the except for Fully Assembled at The TWO included Easy to Solder and headers. Here at The the specs are: Support for the Arduino the IDE at The 1.0+ (OSX / the Win / the Linux) the Power Via the USB or the Source External - 5V or 7-35v (Recommended 12V or less, Automatic Selection) the On-Board Regulator 5V 500mA Built-in the USB . 6 the I / O Pins (2 are Used for only the USB IF your Program actively communicates over the USB, otherwise you CAN use All. 6 the even IF you are Programming Via the USB) 8k the Flash Memory (the About 6K the After the bootloader) the I2C and the SPI (VIS the USI) the PWM ON 3 pins (More Possible the with Software the PWM) the ADC ON 4 pins power led and status

Specification:
Supports Arduino IDE 1.0+ (OSX/Win/Linux).
Can be Powered By USB, 5v or 7-35v external power (automaticlly match).
A 5V/500mA Regulator is on board.
Built-in USB (Serial debugging).
6 I/O Pins (2 are used for USB only if your program actively communicates over USB, otherwise you can use all 6 even if you are programming via USB).
8k Flash Memory (about 6k after bootloader).
I2C and SPI (vis USI).
PWM on 3 pins (more possible with Software PWM).
ADC on 4 pins.
Power LED and Test/Status LED (on Pin0).
