According to LadyAda, both work the same but have different operating logic voltages. There are currently two versions of the Trinket: 3V and 5V. You canвЂ™t stack a big shield on it but for many small and simple projects the Trinket will be your go-to platform.вЂќ вЂњIn fact we even made some simple modifications to the Arduino IDE so that it works like a mini-Arduino board. вЂњWe designed a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino,вЂќ Fried continued. вЂњ perfect for when you donвЂ™t want to give up your expensive dev-board and you arenвЂ™t willing to take apart the project you worked so hard to design.вЂќДЇried describes the Attiny85 as a вЂњfun processor,вЂќ because despite being so small, it boasts 8K of flash and 5 I/O pins вЂ“ including analog inputs and PWM вЂanalogвЂ™ outputs. вЂњWe wanted to design a microcontroller board that was small enough to fit into any project вЂ“ and low cost enough to use without hesitation,вЂќ AdafruitвЂ™s Limor Fried (aka LadyAda) explained.

Reset button for entering the bootloader or restarting the program.Adafruit has launched the Trinket, a tiny microcontroller board built around AtmelвЂ™s ATtiny85.

On-board green power LED and red pin #13 LED.

Power with either USB or external output (such as a battery) - it'll automatically switch over.

Up to 16V input, reverse-polarity protection, thermal and current-limit protection.

On-board 5.0V power regulator with 150mA output capability and ultra-low dropout.

Micro-USB jack for power and/or USB uploading, you can put it in a box or tape it up and use any USB cable for when you want to reprogram.

Also has headers for an FTDI port for reprogramming.

USB bootloader with a nice LED indicator looks just like a USBtinyISP so you can program it with AVRdude and/or the Arduino IDEВ (with a few simple config modifications).

The bootloader does not affect RAM usage.

The bootloader on the Pro Trinket uses 4KB of FLASH so the maximum sketch size is 28,672 bytes.

The USB connection is for uploading new code only.

This is to keep the Pro Trinket small and inexpensive, you can use any FTDI cable to connect to the FTDI port for a Serial connection. There is no Serial-to-USB chip onboard.You cannot plug shields directly into the Pro Trinket.

The onboard 5V regulator can provide 150mA output, not 800mA out.

Pins #2 and #7 are not available (they are exclusively for USB).

Here's some things you may have to consider when adapting Arduino sketches: So you'll be happy to hear that not only is Pro Trinket programmable using the Arduino IDE as you already set up, but 99% of Arduino projects will work out of the box! The Pro Trinket 5V uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. So it's great once you've finished up a prototype on an official Arduino UNO and want to make the project smaller. The Pro Trinket PCB measures only 1.5' x 0.7' x 0.2' (without headers) but packs much of the same capability as an Arduino UNO. Note: You will need a USB micro B cable to power and to program this board, so grab this cable here if you don't have one. Adafruit also added Optiboot support, so you can either program your Pro Trinket over USB or with an FTDI cable just like the PRO Mini using UC00A or UC00C. Like the Trinket, it has onboard USB bootloading support - AdafruitВ opted for a MicroUSB jack this time. That's why AdafruitВ designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM. While it hasВ been great to see tons of tiny projects, sometimes you just need more pins, more FLASH, and more RAM. It's like an Arduino Pro Mini with more pins and USB tossed in, so delicious. Trinket's got a big sister in town - theВ Pro Trinket 5V! Pro Trinket combines everything you love about Trinket with the familiarity of the common core Arduino chip, the ATmega328. please take EXTRA PRECAUTION while doing soldering works.
