Pro Trinket combines everything you love about Trinket with the familiarity of the core Arduino chip, the ATmega328. It’s like an Arduino Pro Mini with more pins and USB tossed in.
Adafruit designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM.
Like the Trinket, it has onboard USB bootloading support – Adafruit opted for a MicroUSB jack this time. Added Optiboot support, so you can either program your Pro Trinket over USB or with a FTDI cable just like the Pro Mini and friends.
The Pro Trinket PCB measures only 1.5″ x 0.7″ x 0.2″ (without headers) but packs the same capability as an Arduino UNO. 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 uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. Pro Trinket is programmable using the Arduino IDE as you already set up, and 95% of Arduino projects will work out of the box!

Here’s some things you may have to consider when adapting Arduino sketches:
Development Boards & Kits – AVR Pro Trinket 5V 16MHz (1 piece)
$50.99
- Make sure this fits by entering your model number.
- ATmega328P onboad chip in QFN package. 16MHz clock rate, 28K FLASH available
- USB bootloader with a nice LED indicator looks just like a USBtinyISP so you can program it with AVRdude and/or the Arduino IDE (with a few simple config modifications). Also has headers for an FTDI port for reprogramming
- 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.
- On-board 3.3V/5V power regulator with 150mA output capability and ultra-low dropout. Up to 16V input, reverse-polarity protection, thermal and current-limit protection. Power with either USB or external output (such as a battery) – it’ll automatically switch over. On-board green power LED and red pin #13 LED
- Reset button for entering the bootloader or restarting the program. Works with 99% of existing Arduino sketches (anything that doesn’t use more than 28K, and doesn’t require pins #2 and #7)
