This tiny development board is based on the Attiny85 microcontroller and is perfect for projects that require a tiny footprint and just a few IO pins.

• Support for the Arduino IDE (OSX/Win/Linux)
• Power via micro USB or External Source 5V or 7-15V (12V or less recommended, automatic selection).
• On-board 100mA 5V Regulator.
• 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 (via USI)
• PWM on 3 pins (more possible with Software PWM)
• ADC on 4 pins 9. Power LED and Test/Status LED

Includes male headers (unassembled)
