Digispark ATtiny85 Arduino-enabled Mini USB Dev Board

Complete USB Dev Board Cheap Enough to Leave in a Project

If you have never heard of the Digispark ATtiny board before, it may take you more than a moment to understand its full power and potential. So read this carefully: 

Firstly, it's a 20MHz, AVR 8-bit microcontroller with 8 KB flash, 512 bytes of RAM  (See the datasheet)

You get up to 5 GPIOs, 4 ADCs, 2 PWMs, 1 SPI and 1 I2C[*] 

Secondly, it's fully compatible with Arduino (See instructions here)

Thirdly, it can be directly programmed via USB without needing any other programmer!

And finally, it is available at cheap price!!

[*] There are only a total of 6 pins, so you can't get everything at the same time, of course.

This board was first launched in late 2012 on Kickstarter where it raised $300,000+ in just 30 days.  And till today, it remains one of the most popular choices for quick one-off projects that require a controller.  Here are some examples from Instructables:

 

 

Before You Buy

Some soldering required: We send you the board, one 6 pin header and 1 3-pin header (see the second picture in the listing).   You need to solder the pins yourself before you can connect other components to it.

USB Emulation: The micro (ATTiny85) does not have a proper USB peripheral.  Instead it emulates a USB device during boot (you can also use this emulated USB after boot if you want).  See here for details

Uploading a Sketch: Due to this USB emulation, the uploading procedure is slightly different for this board compared to normal Arduino.  Please follow the instructions in the digistump wiki 

This is a great low cost development board, but it is not a full-fledged Arduino.
