Description Attiny85 Mini_USB Development Board The Attiny85 Mini_USB Development Board is similar to the Arduino line but cheaper. It caters to projects that need a low IO pin count. If you need more pins but still small in size you could use the Arduino Nano as well. About the USB Digispark is an Attiny85 based microcontroller development board similar to the for Arduino 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 for Arduino IDE the Digispark is a great way to jump into electronics, or perfect for when an for Arduino is too big or too much. Feature: 1. Support for Arduino IDE 1.0 (OSX/Win/Linux). 2. Power via USB or External Source – 5v or 7-15v (12v or less recommended, automatic selection). 3. On-board 500ma 5V Regulator. 4. Built-in USB 5. 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) 6. 8k Flash Memory (about 6k after bootloader) 7. I2C and SPI (via USI) 8. PWM on 3 pins (more possible with Software PWM) 9. ADC on 4 pins 10. Power LED and Test/Status LED 11. Operating voltage: 3.3 V
