Digispark ATTINY85 Mini USB Development Board | Arduino Compatible Microcontroller Board

The Digispark ATTINY85 Mini USB Development Board is a compact yet powerful Arduino-compatible microcontroller board based on the ATtiny85 chip. Despite its small size, it delivers robust performance and flexibility for a wide range of DIY electronics, IoT, and automation projects.

Powered by a 20MHz 8-bit AVR microcontroller, the Digispark ATTINY85 features up to 5 GPIO pins, 4 ADCs, 2 PWM outputs, and built-in SPI and I2C communication capabilities. It can be directly programmed via USB — no external programmer required — making it one of the easiest and most affordable ways to start with embedded development.

This tiny board is ideal for quick prototypes, wearable electronics, mini gadgets, and educational projects. Whether you’re designing a POV display, mood light, mini weather station, or custom USB device, the Digispark offers impressive versatility at a budget-friendly price.

Note: Basic soldering is required before use. USB functionality is emulated through firmware, as the ATTiny85 lacks native USB hardware.
