Electronics for IoT, Prototyping & DIY

The Digispark ATtiny85 is a tiny, Arduino-compatible development board built around the Microchip ATtiny85 microcontroller. It features a built-in USB-A plug that connects directly to your computer for programming and power -- no cables needed. Despite being smaller than a quarter, it packs 6 I/O pins, PWM, analog inputs, and a USB bootloader that lets you program it directly from the Arduino IDE.

⚠️ Important: The Digispark programs differently than other Arduino boards. Click Upload in the Arduino IDE first, then plug in the board when prompted. The bootloader only listens for new code for ~5 seconds after power-on. See the User Guide on our support website for more details and extensive programming instructions.⚡ Key Features

Built-In USB-A Plug -- Plugs directly into any USB-A port; no cables required
Ultra-Compact Design -- Smaller than a quarter; perfect for embedded and portable projects
Arduino IDE Compatible -- Program using the familiar Arduino IDE with Digistump board support
Micronucleus USB Bootloader -- Upload sketches directly over USB; no external programmer needed
6 I/O Pins -- Digital I/O, 3 PWM outputs, and 4 analog input channels
On-Board LED -- Built-in LED on pin P1 for testing and debugging
On-Board 5V Regulator -- Also accepts 7–12V on VIN pin for standalone operation
USB HID Capable -- Emulate USB keyboards, mice, and other HID devices

🎯 Typical Applications

USB HID devices -- custom keyboards, macro pads, and mouse emulators
LED controllers and RGB lighting effects
Sensor data logging (temperature, light, humidity)
Wearable electronics and compact embedded projects
Home automation triggers and IoT sensor nodes
Educational projects and learning Arduino programming
Rapid prototyping of simple control circuits

⚠️ Important Notes

Click Upload in the Arduino IDE first, then plug in the board when prompted. Do not plug in before clicking Upload.
Windows users must install Digistump USB drivers before first use.
The ATtiny85 does not have a hardware UART -- the standard Arduino Serial Monitor is not available.
With ~6 KB of usable flash memory, keep sketches small and avoid large libraries.
Pin P5 is the RESET pin. Reconfiguring it as I/O will permanently disable USB programming.
For best results, use a USB 2.0 port. Some USB 3.0 controllers may have compatibility issues with low-speed USB devices.
