BeanDuino Attiny85 – super small Digispark clone

The BeanDuino is an ATtiny85 based microcontroller development board similar to the Arduino line highly inspired by DigiSpark , BeanDuino is hardware compatible with Adafruit Trinket / Gemma.

Specifications:

  • Support for the Arduino IDE 1.0 and later (OS X, Windows, and Linux)
  • Built-in USB
  • 5 I/O pins (2 are used for USB only if your program actively communicates over USB, otherwise you can use all 5 even if you are programming via USB) or 6 I/O pins if you dissable reset fuse
  • 8 KB flash memory (about 6 KB after bootloader)
  • I2C and SPI (vis USI)
  • PWM on 3 pins (more possible with software PWM)
  • ADC on 4 pins
  • Internal temperature sensor
  • On-board PB1 led – no shield required !!!
  • Keyboard or other HID devices emulation (mouse, gamepad …)
  • reset is enabled you can program this board with USBASP or Arduino via ISP you can easy replace/repair/remove bootloader
  • slim design 11×20 mm
  • breadboard compatible

Introduction to Digispark

runtimeprojects.com has a quick review of the Digispark board. It’s a really interesting mini board that can be used in small projects using Arduino IDE.

In today’s blog post we’ll analyze one of the smallest and most practical boards out there. The Digispark board. It’s size, including the USB port, is 25mm x 18mm (so tiny)!! This little board is powered by an ATTINY85 chip and clocked to 16.5Mhz. For conveniece, it has a built in USB port and can be plugged into a your computer without cables or adapters. Now that’s pretty awesome! It is powered by either the USB port, from the +5v pin with regulated 5v or from VIN pin if unregulated. The VIN pin supports from 7v to 35v although less than 12v is recommended by the manufecturer.
