Digispark ATtiny85 USB Development Board

Digispark ATtiny85 USB Development Board

Meet the Digispark — the tiny, Arduino-compatible microcontroller board that punches well above its weight. Built around the powerful ATtiny85 chip, this compact board plugs directly into any USB port and is programmable via the Arduino IDE. It's the perfect tool for small automation tasks, wearable projects, and space-constrained builds where a full-sized Arduino would be overkill.

Key Features

• Microcontroller: Atmel ATtiny85
• Clock Speed: 16 MHz (internal)
• Operating Voltage: 5V (USB) or 7–35V (VIN)
• I/O Pins: 6 (P0–P5), including PWM and analog input
• Flash Memory: 8 KB (6 KB usable after bootloader)
• SRAM: 512 Bytes
• EEPROM: 512 Bytes
• USB Interface: Built-in Micro-USB connector
• On-board LED: Connected to P1
• Arduino IDE Compatible: Program using the Digistump board package

Typical Applications

• USB HID devices (keyboard/mouse emulation)
• Wearable electronics and compact IoT nodes
• LED controllers and PWM projects
• Sensor data loggers
• Automation scripts and macros
