You can't stack a big shield on it but for many small & simple projects the Trinket will be your go-to platform.

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

We 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 our lowest-cost arduino-IDE programmable board!Īs of May 27th, 2015 the 3.3V Trinket has been revised! The board is now even smaller – at just 27mm x 15mm – and comes with a micro-B USB connector rather than mini-B 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. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. 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.
