Adafruit Pro Trinket – 5V & 3V sold out instantly – making more now!

2000-03

The Adafruit Pro Trinket – 5V & 3V sold out instantly again… we’re increasing the amount we make each time and making more right now, thanks for hanging in there. The Pro Trinket is a “breakout hit” as they say in the breakout business.

Pro Trinket combines everything you love about Trinket with the familiarity of the common core Arduino chip, the ATmega328. It’s like an Arduino Pro Mini with more pins and USB tossed in, so delicious.

Trinket’s a year old now, and while its been great to see tons of tiny projects, sometimes you just need more pins, more FLASH, and more RAM. That’s why we 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 – we opted for a MicroUSB jack this time. We also 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 much of 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 5V uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. at the same speed and voltage. 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!

  1. Will there ever be a trinket with a builtin 3.3V/5V level shifter that you can assign to pins? Or even just making half the pins be 3.3V and the other side of the board be 5V compatible would be awesome!

    I’m not sure how you would split up the ports, but when I was making my pinewood derby car with acceleration detection, it was a total pain trying to figure out which board to use since I needed 5V for the LEDs (sorta kinda) but 3.3V for the Accelerometer breakout board.

    It was just frustrating having to mix and match and futz around.

  2. We have level shifting for all our breakouts so you can use any accelerometer in the store with 5V power & logic.
