In fact Adafruit even made some simple modifications to the Arduino IDE so that it works like a mini-Arduino board.

Adafruit designed a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino.

The Attiny85 is a fun processor because despite being so small, it has 8K of flash, and 5 I/O pins, including analog inputs and PWM 'analog' outputs. It's the lowest-cost arduino-IDE programmable board! Perfect for when you don't want to give up your expensive dev-board and you aren't willing to take apart the project you worked so hard to design. This tiny board is designed by Adafruit, they wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. The Trinket may be small, but do not be fooled by its size! It's a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. please take EXTRA PRECAUTION while doing soldering works. Note:This module comes with loose headers, so soldering is required. Lithium Ion Rechargeable Battery and Charger.
