Miniature TINY85 Arduino USB Development Board based on Attiny85 MCU
This tiny and low cost AVR development board is great for compact projects or projects that only requires a few IO pins. Based on the 8 pin Atmel ATTiny85 processor it allows for an incredibly small form factor. It also has the advantage of including a micro usb interface that allows the processor to be programmed via a USB power without the need for any download adapters. Additionally the board also comes pre-programmed with the Arduino bootloader and test blink sketch. Please note that to use with the Arduino development environment you will need a modified version of this software (see below).
This development board is based on the DigiStump Digispark reference design.
