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 - Adafruit opted for a MicroUSB jack this time. That's why Adafruit designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM. While it has 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 - the 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. Note:This board comes with loose headers, so soldering is required. Lithium Ion Rechargeable Battery and Charger.Lead Acid Rechargeable Battery and Charger.Hardware I2C / SPI capability for breakout & sensor interfacing.The 2 shared IO pins have 2 more analog inputs and one more PWM output. The 3 independent IO pins have 1 analog input and 2 PWM output as well. 5 GPIO - 2 shared with the USB interface.No need to unplug/replug the board every time you want to reset or update! Reset button for entering the boot-loader or restarting the program.On-board green power LED and red pin #1 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 3.3V or 5V power regulator with 150mA output capability and ultra-low dropout.

~5.25K bytes available for use (2.75K taken for the boot-loader).

Adafruit really worked hard on the boot-loader process to make it rugged and foolproof, this board wont up and die on you in the middle of a project!.

Mini-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.

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

ATtiny85 on-board, 8K of flash, 512 byte of SRAM, 512 bytes of EEPROM.

You can't stack a big shield on it but for many small & simple projects the Trinket will be your go-to platform. In fact they even made some simple modifications to the Arduino IDE so that it works like a mini-Arduino board.

Adafruit designed a USB boot-loader so you can plug it into any computer and reprogram it over a USB port just like an Arduino. The Attiny85 is a fun processor because despite being so small, it has 8K of flash, and 5 I/O pins, including analog inputs and PWM 'analog' outputs. It's their lowest-cost arduino-IDE programmable board! Perfect for when you don't want to give up your expensive dev-board and you aren't willing to take apart the project you worked so hard to design. As of October 9th, 2015 the 5V Trinket comes with a micro-USB connector instead of a mini-USB connector!Īdafruit wanted to design a micro-controller board that was small enough to fit into any project, and low cost enough to use without hesitation. 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. 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.
