Digispark ATTINY85 Mini USB Development Board

Digispark ATTINY85 Mini USB Development Board is Arduino-enabled Mini USB Dev Board which is enough to Live 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 
• You get up to 5 GPIOs, 4 ADCs, 2 PWMs, 1 SPI and 1 I2C[*]
• Secondly, it’s fully compatible with Arduino
• 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 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:

• Wearable ring watch
• POV Display
• Mini Weather Station
• Mood Light
• …And Many More!

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