This Digispark compatible development board is an Attiny85 based microcontroller board similar to the Arduino line, only cheaper, smaller, and simpler. Mini ATtiny85 USB Development Board is suitable for controlling a few I/O lines in small projects. 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 to jump into electronics, or perfect for when an Arduino board is too big or too much. This Digispark compatible board is shipped fully assembled except for the two included and easy to solder pin headers.
Support for Arduino IDE 1.0+ (OSX/Win/Linux).
Power via USB or External Source - 5V or 7-35V (automatic selection).
On-board 500mA 5V Regulator.
Built-in USB (and 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).
