Digispark ATtiny85 USB Development Board – Microcontroller Module

The Digispark ATtiny85 USB Development Board is a small microcontroller platform designed for embedded projects and rapid prototyping. It is based on the ATtiny85 microcontroller, offering integrated USB connectivity for direct programming without external interfaces. The board provides stable performance with multiple digital I/O pins, PWM support, and I2C communication, ensuring reliable operation for a wide range of applications. It is suitable for sensor interfacing, automation modules, wearable devices, and educational embedded systems.
