Details

A tiny, affordable, Arduino-enabled, USB development board.

A micro-sized, affordable, Arduino enabled, USB development board!

The Digispark is an Attiny85 based microcontroller development board similar to the Arduino line, only cheaper, smaller (about the size of a quarter), and a bit less powerful. With a whole host of shields to extend its functionality and the ability to use the familiar Arduino IDE the Digispark is a great way to jump into electronics, or perfect for when an Arduino is too big or too expensive.

The Digispark is shipped fully assembled except for the two included and easy to solder headers.

Specifications

  • Support for the Arduino IDE 1.0+ (OSX/Win/Linux)
  • Power via USB or External Source - 5v or 7-35v (automatic selection)
  • On-board 500ma 5V Regulator
  • Built-in USB
  • 6 I/O Pins (2 are used for USB only if your program actively communicates over USB, otherwise you can use all 6 even if you are programming via USB)
  • 8k Flash Memory (about 6k after bootloader)
  • I2C and SPI (vis USI)
  • PWM on 3 pins (more possible with Software PWM)
  • ADC on 4 pins
  • Power LED and Test/Status LED

Digistump RGB Shield Kit*

Great for beginning hobbyists, the RGB Shield Kit allows you to build a Digispark shield that connects a Red-Green-Blue tri-colored LED to the Digispark development board. Using the PWM (Pulse Width Modulation) features of the Digispark you can mix the three colors to achieve millions of different shades. Use it as a status indicator, a light show, or even connect it to your computer and change the color remotely.


Prototype Shield Kit*

The Prototype Shield Kit breaks out the connections on the Digispark development board and provides a small through hole soldering area for building custom circuits.


Breakout Kit Ver. A*

The Breakout Shield Kit breaks out each i/o connection on the Digispark development board and provides them as three pin headers with a 5V, Gnd, and i/o pin for each. This allows the easy connection of third-party and homemade sensors, servos, and more. The Version A kit provides headers in the order of GND / 5V / I/O Pin Version B kit provides headers in the order of GND / I/O Pin / 5V


EEPROM Memory Kit*

The EEPROM Shield Kit allows you to build a Digispark shield which connects a 256Kbit Serial Electrically Erasable PROM (EEPROM) memory IC to the Digispark development board. The IC used is the Microchip 24LC256 and it communicates with the Digispark over the I2C bus. The EEPROM Shield can be used to store data even after the device is powered off. The IC has an endurance rating of over 1 million write/erase cycles and its rated data retention is more than 200 years.


MOSFET Kit*

The MOSFET Shield Kit connects a 60V 30A N-Channel MOSFET to the Digispark development board. This allows the Digispark to turn DC loads on and off and use PWM with larger loads. The MOSFET is rated for 30A, but should be used at a far lower amperage without additional cooling.


I/O Expander Kit*

The Expander Shield Kit allows you to build a Digispark shield which connects a PCF8574P Remote 8-bit I/O expander IC to the Digispark development board. It communicates with the Digispark over the I2C bus and provides 8 more digital i/o pins that can be controlled by the Digispark.


Relay Kit*

The Relay Shield Kit connects a Omron G5Q relay to the Digispark development board. This allows the Digispark to turn AC and DC loads on and off up to 250VAC. The relay is rated for 3A@125VAC, 3A@250VAC, and 5A@30VDC.


Motor Driver Kit*

The Motor Shield Kit allows you to connect two DC motors to the Digispark development board. The Motor Shield connects the TB6612FNG Dual Motor Driver to the Digispark allowing the Digispark to control up to two DC motors, up to 15VDC, 1.2A per channel (3.2A peak). The Motor Shield kit uses two inverters to allow each motor attached to the TB6612FNG to be controlled with only two i/o lines from the Digispark, four total.


Boost Kit*

The Boost Shield Kit allows you to use supply voltages under 5v with the Digispark development board. The Boost Shield boosts a 2-4.5v supply (including 2 aa or aaa batteries, or on lipoly) to 5v and connects directly to the Digispark.


I2C LCD Kit*

The LCD Shield Kit allows you to build a Digispark shield which connects a 16x2 I2C LCD display to the Digispark development board. It communicates with the Digispark over the I2C bus and allows the Digispark to output text and characters such as sensor reading and debugging information. The included I2C LCD is White on Blue and backlit.

This kit is based on the MintyBoost design by Adafruit!


*This is an unassembled kit and requires basic soldering. This is designed for use with the Digispark development board, which is not included.

Digistump History

In August 2012, Erik launched the Digispark on Kickstarter, raising over $300,000 in 30 days, enabling him to bring the Digistump product lineup to market.
