Adafruit PRO Trinket - 5V 16MHz
- Brands Adafruit Code: AF-TKPRO-5V
Note: This board comes with loose headers, so soldering is required. please take EXTRA PRECAUTION while doing soldering works. We don't want you to get burnt.
Trinket's got a big sister in town - the Pro Trinket 5V! 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.
While it has been great to see tons of tiny projects, sometimes you just need more pins, more FLASH, and more RAM. That's why 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. 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.
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.
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!
