Digispark ATTINY85 USB Micro Development Board Arduino Compatible Blue Module

🔧 Digispark ATTINY85 USB Micro Development Board Blue | AuscomTech

A compact ATTINY85-based microcontroller board designed for small Arduino-compatible projects, embedded control, and tight-space electronics builds.

It provides built-in USB programming, 6 usable I/O pins, PWM outputs, ADC inputs, I2C, and SPI support via USI.

Typical use includes mini automation projects, sensor interfaces, LED control, USB-enabled circuits, and low-pin-count microcontroller development.

⭐ Key Features

• Arduino IDE Support – compatible with Arduino IDE 1.0+ on Windows, macOS, and Linux.
• Built-In USB Interface – supports USB programming and serial debugging without a separate programmer.
• Flexible Power Input – can be powered via USB or external supply with automatic selection.
• Onboard 5V Regulator – includes a 150mA 5V regulator for stable board operation.
• 6 I/O Pins – provides six digital pins, with USB using two pins only when the program actively communicates over USB.
• PWM & ADC Support – PWM available on 3 pins, with ADC input on 4 pins.
• Compact PCB Size – small 18.0 × 22.8mm board footprint for embedded projects.
