Digispark ATtiny85 Arduino compatible USB board is designed for programming, monitoring, control in various projects that require the use of microcontrollers or can be connected to software running on a computer. The Digispark USB controller can replace Arduino controllers in projects where size is important and a lot of power is not needed. The Digispark USB controller is fully compatible with the Arduino IDE software and code written in this environment. Digispark has support for all the features available in the IDE. The exception is the serial monitor and bootloader entry. The Digispark USB controller is a great device for beginner developers.
Before using Digispark USB, you need to download and install the Arduino IDE software on your computer
Arduino IDE software . Then you need to download and install
the driver to work with the board. After that, you can connect the controller directly (preferably via an extension cable) to the USB port of your computer. Your operating system should automatically overtake the controller. When power is applied, the red power LED on the controller board will light up. Next, you need to
install the Digispark board in the Arduino IDE. After that, you can start working with the controller. The controller comes with pin contacts. If necessary, the pins can be soldered to the controller board.
The board has contacts for connecting power and controlled devices "5V", "GND", "VIN". If the voltage of the external power supply is 5 V, then it is connected to the contacts "5V", "GND". Thanks to the built-in voltage regulator, an external power source with a voltage of 7 - 35 V can be connected to the controller. You need to connect such a source to the pins "VIN", "GND".
Main characteristics:
-
Support for Arduino IDE 1.6.5 and later (OS X, Windows and Linux)
-
Powered by USB or external source - 5V or 7-35V
-
5V 500mA regulator when powered from an external source.
-
Built-in USB

Description of conclusions:
All pins can be used as digital inputs/outputs
Pin 0 → AREF (ADC reference voltage), I2C SDA (Serial Data), PWM (PWM)
Pin 1 → DO (MISO), PWM (PWM), LED (LED )
Pin 2 → D/A (digital, analog input-output), I2C SCK (Serial Clock).
Pin 3 → D/A (digital, analog input-output). Busy USB+pin, if using USB.
Pin 4 → D/A (digital, analog input-output), PWM (PWM). Occupied by USB- pin, if using USB.
Pin 5 → D/A (digital, analog input-output).
