ATTiny85 Module (Digispark) Spec.

• Support for the Arduino IDE 1.0 + (OSX/Windows/Linux).
• Power via USB or External Source or 7-16 v to 5 v (automatic selection).
• The On - board, 150 ma 5 v Regulator.
• Built - in USB and serial was debugging).
• 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).
• 8 k Flash Memory (about 6 k after bootloader).
• The I2C and SPI (vis USI).
• PWM on 3 pins (more possible with Software PWM).
• The ADC on 4 pins.
• The Power LED and the Test/Status leds.

ATTiny85 Module (Digispark) Pinout

• 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
