The Specs:

1. Support for the Arduino IDE 1.0 + (OSX/Windows/Linux).

2. Power via USB or External Source or 7-16 v to 5 v (automatic selection).

3. The On - board, 150 ma 5 v Regulator.

4. Built - in USB and serial was debugging).

5. 6 I/O Pins (2 are informs the for USB only if your program actively communicates over USB, otherwise you can use all 6 even if you are programming via USB).

6. 8 k Flash Memory (about 6 k after bootloader).

7. The I2C and SPI (vis USI).

8. PWM on 3 pins (more possible with Software PWM).

9. The ADC on 4 pins.

10. The Power LED and the Test/Status leds.

Installing Digispark USB driver

Digispark use USB to communicate with computer, so your computer must install Digispark USB driver

1. Download Arduino for Digispark which come with USB driver

2. Extract the file (DigisparkArduino-Win32-1.0.4-March29.zip)  to any folder

3. Execute DigisparkArduino-Win32\DigisparkWindowsDriver\InstallDriver.exe to start installing the USB driver

■ ATTiny85 Module Pin 정의

All pins can be used as Digital I/O (모든 핀들은 디지털 I/O 핀으로 사용 가능함)

Pin 0 → I2C SDA, PWM (LED on Model B)

Pin 1 → PWM (LED on Model A)

Pin 2 → I2C SCK, Analog In

Pin 3 → Analog In (also used for USB+ when USB is in use)

Pin 4 → PWM, Analog (also used for USB- when USB is in use)

Pin 5 → Analog In
