Today we’re profiling our own line of Trinket development boards.
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 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!
To get you started with seeing how easily the Trinket can be deployed for projects, check out this Blinky Eyes Learn Guide – replace a full-sized Arduino with something much more discreet for something so simple and specific:
The Trinkets are breadboardy-ready, which we all typically have plenty laying around. This allows Trinket projects to be quickly prototyped. This specific project assumes the 3V Trinket is used with the LEDs and resistors shown – the 5V Trinket is also applicable but would require changing the resistor/s required.
Which is to say the 3V and 5V Trinkets are very similar, save the logic voltage of the two devices. To show what is possible with a 5V Trinket running at 16.5MHz check out this simple implementation of the Trinket as a keyboard input device:
That seems simple now, but you can imagine this wasn’t so easy in the early days of Arduino-compatible microcontroller projects – for example the code that powers this input is only 47 lines long (and many of that are comment lines that could be removed). And you can quickly expand or modify the provided code to become your own keyboard-input solution.
If you like the Trinket package but are looking for a bit more punch, perhaps using the more familiar ATmega328 processor, the Pro Trinkets are for you! They’re also available in 3V and 5V flavors, and carry a sizeable 28K FLASH (compared with 8K provided by the ATtiny-based non-Pro Trinkets).
For comparisons sake the image below shows the Trinket Pro on the left and the non-Pro Trinket on the right – both are the 5V models:

Adafruit Holiday Shipping Deadlines 2017
Here are your 2017 shipping deadlines for ordering from Adafruit. Please review our shipping section if you have specific questions on how and where we ship worldwide for this holiday season.
The Adafruit Shipping Department works hard to get your orders out as quickly as we can, but once they’re in the hands of our carriers they’re out of our control. Carriers have been struggling to keep up with the sharp rise in online orders. UPS, FedEX, and USPS all experienced delivery delays over the last few years.
So all the Adafruit Shippers say: Please be sure you get your gifts early! Order as soon as you can! Once you place your order we’ll ship like the wind!
