The Trinket may be small, but do not be fooled by its size! It's a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. This tiny board is designed by Adafruit, they wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. 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. It's the lowest-cost arduino-IDE programmable board!

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. Adafruit designed a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino. In fact Adafruit even made some simple modifications to the Arduino IDE so that it works like a mini-Arduino board. You can't stack a big shield on it but for many small & simple projects, the Trinket will be your go-to platform.

Even though you can program Trinket using the Arduino IDE, it's not a fully 100% Arduino-compatible. There are some things you trade-off for such a small and low-cost microcontroller!

  • Trinket DOES NOT have a Serial port connection for debugging so the serial port monitor will not be able to send/receive data
  • Some computers' USB v3 ports don't recognize the Trinket's bootloader. Simply use a USB v2 port or a USB hub in between

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.

Features and specifications:

  • ATtiny85 on-board, 8K of flash, 512 bytes of SRAM, 512 bytes of EEPROM
  • The internal oscillator runs at 8MHz but can be doubled in software for 16MHz
  • USB bootloader 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)
  • 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.
  • Adafruit really worked hard on the bootloader process to make it rugged and foolproof, this board won't up and die on you in the middle of a project!
  • ~5.25K bytes available for use (2.75K taken for the bootloader)
  • On-board 5.0V 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 #1 LED
  • Reset button for entering the bootloader or restarting the program. No need to unplug/replug the board every time you want to reset or update!
  • 5 GPIO - 2 shared with the USB interface. The 3 independent IO pins have 1 analog input and 2 PWM output as well. The 2 shared IO pins have 2 more analog inputs and one more PWM output.
  • Hardware I2C / SPI capability for breakout & sensor interfacing.
  • Works with many basic Arduino libraries including Adafruit Neopixel!
  • 2 mounting holes on board!
  • Really really small, just about the size of your thumb.
