![]() ![]() ![]() The 5V version can run at 8 MHz or at 16MHz by setting the software-set clock frequency. Use the 5V one for sensors and components that can use or require 5V logic.As 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 The 3V3 version should only run at 8 MHz. 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.Both work the same, but have different operating logic voltages. Dimensions: 1.2″ x 0.6″ x 0.2″ / 31mm x 15.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.Reset button for entering bootloader or restarting the program. ![]() 5 I/O pins – 3 analog and 3 PWM shared between the pins.Adafruit has done an amazing job by providing a bootloader that allows USB programming but because of this, the available programming room is decreased by 2.75K. Please note: that there is only 5.25K of usable programming space (6 times smaller than the Arduino UNO) which means that this board should only be used to program simple projects. The Trinket has to be one of the smallest USB enabled Arduino compatible microcontrollers we’ve seen yet! This pretty little thing is great for when you want to keep you electronics project hidden, low-cost, and simple. ![]()
