Product Description
The ATtiny85 USB Development Board is a versatile, ultra-compact prototyping board built around the powerful yet minimal ATtiny85 8-bit AVR microcontroller. Designed as a smaller, more affordable alternative to traditional Arduino boards, this module is perfect for projects where space, simplicity, and efficiency are key.
This board simplifies the development process by integrating a direct USB interface, eliminating the need for bulky external programmers. It comes pre-flashed with a special bootloader (commonly Micronucleus or similar), allowing it to be programmed effortlessly using the familiar Arduino IDE environment. Simply plug it into any computer USB port, upload your code, and you are ready to go.
Despite its diminutive size, the ATtiny85 chip packs a punch with 8KB of Flash memory and access to multiple I/O pins that support Digital I/O, Pulse Width Modulation (PWM) for smooth LED fading or motor control, and Analog-to-Digital Conversion (ADC) for reading sensors. This robust functionality, combined with its breadboard-friendly design and integrated voltage regulation, makes it an ideal choice for creating small, embeddable gadgets, wearable electronics, sensor interfaces, and countless other custom DIY projects.
