Product Description
"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.
We wanted to design a microcontroller 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 devboard 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!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.
We designed a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino.
In fact we even made some simple modifications to the Arduino IDE so that it works like a mini-Arduino board.
You can't stack a big shield on it but for many small & simple projects the Trinket will be your go-to platform.
