ATtiny85 Module with Micro USB — Digispark Compatible

ATtiny85 Module with Micro USB — Digispark Compatible

The ATtiny85 Micro USB module is a Digispark-compatible development board — the smallest Arduino-compatible board available. Powered and programmed via Micro USB, it runs the ATtiny85 AVR microcontroller with 8KB flash and 6 usable I/O pins. Program it directly from the Arduino IDE using the Digispark board package — no external programmer required.

Key Specifications

• MCU: ATtiny85 | Clock: 16.5MHz (USB mode) / 8MHz (standalone)
• Flash: 8KB (6KB usable after bootloader) | SRAM: 512B | EEPROM: 512B
• I/O pins: 6 (including 4 ADC, 2 PWM) | USB: Micro USB (programming + power)
• Operating voltage: 5V (USB) / 3.3V–5V (external) | On-board regulator: 5V & 3.3V
• IDE: Arduino IDE compatible (Digispark board package)
• Compliance: RoHS compliant

Why Choose This?

• ✅ Smallest Arduino-compatible board — ideal for wearables, hidden installations and space-critical projects
• ✅ Micro USB programming — no external programmer, plug in and upload from Arduino IDE
• ✅ 5V & 3.3V on-board — power sensors and peripherals directly from the board
• ✅ Low power — ideal for battery-powered projects with sleep modes

Typical Applications

• Wearable electronics and compact IoT devices
• USB HID devices (keyboard, mouse emulation)
• Simple automation and sensor reading projects
• Low-power battery-operated embedded systems
