ATTINY85 Digispark Kickstarter USB ARDUINO

Digispark is a miniature arduino compatible board based on the ATtiny85 microprocessor. The device is compatible with Arduino IDE. An ideal solution for relatively simple projects, it contributes to their significant reduction in cost and size.

This is a new approach to prototyping devices on the ATtiny85 in the Arduino environment. The ATtiny85 is just right for a lot of things where full-fledged Arduino-compatible boards like the Pro Mini, Uno, and even more so the Mega are redundant. Moreover, this particular controller is good because you can quickly, without a web of wires and programmers, run in the code, which will then work fully in something ready.

ATtiny85 is a small microcontroller with decent features and nice features, namely:

- 8 KB of memory for program code, 512B of memory for executable code
- 6 digital pins
- 4 ADC inputs
- 2 PWM outputs
- hardware interrupt
— frequency from 1 MHz to 20 MHz
- power supply from 1.8V to 5.5V (depending on modification)
- current consumption - from 0.1 μA at 1.8V in maximum energy saving mode
- available in miniature SOIC8 or DIP packages

To connect controlled devices, there are six pins on the controller board, labeled P0 - P5. Each of the contacts can perform several functions:

P0 - AREF (ADC reference voltage), SDA (Serial Data), DI (MOSI), PWM (PWM)
P1 - DO (MISO), PWM (PWM)
P2 - D /A (digital, analog input /output), SCK (Serial Clock)
P3 - D /A (digital, analog input /output), USB +
P4 - PWM (PWM), D /A (digital, analog input /output), USB-
P5 - D /A (digital, analog input /output)
