Adafruit Trinket - Mini Microcontroller - 3.3V Logic

*PLEASE NOTE THIS PRODUCT HAS NOW BEEN DISCONTINUED* Trinket may be small, but do not be fooled by its size! It's a tiny micro-controller board, built around the Atmel ATtiny85, a little chip with a lot of power. There are two versions of the Trinket. One is 3V3 and one is 5V. Both work the same, but have different operating logic voltages.

• Use the 3V3 one to interface with sensors and devices that need 3V3 logic, when you want to power it off of a LiPo battery, or if you want to connect it directly to the Raspberry Pi GPIO without logic level converters. The 3V3 version should only run at 8 MHz
• Use the 5V one for sensors and components that can use or require 5V logic. The 5V version can run at 8 MHz or at 16MHz by setting the software-set clock frequency.

We wanted to design a micro-controller board that was small enough to fit into any project, and low cost enough to use without hesitation. 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. It's our lowest-cost arduino-IDE programmable board!
