Trinket is a tiny microcontroller board, built around Atmel ATtiny85 IC, a little chip with a lot of power. Its a low cost, small size board, perfect for when you don't want to use your expensive development board,it's lowest-cost arduino-IDE programmable board.Its comes with 8K flash memory and has 5 GPIO pins, including analog inputs and PWM outputs. Its comes with USB bootloader, so you can plug it into any computer and reprogram it over a USB port just like an Arduino.

This is the 5V Trinket. There are two versions of the Trinket boards available , One is 3V and one is 5V. Both work the same, but have different operating logic voltages.The 3V version should only run at 8 MHz, whereas the 5V version can run at 8 MHz or at 16MHz by setting the software-set clock frequency. Even though you can program Trinket using the Arduino IDE, it's not a fully 100% Arduino-compatible. 


  • 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


  • Memory: 8K of flash, 512 byte of SRAM, 512 bytes of EEPROM
  • Oscillator frequency: 8MHz @ 3V, 8Mhz @ 5V, 16Mhz @ 5V.
  • Loaded with USB bootloader
  • Micro-USB jack for power and/or USB data uploading
  • Bootloader is rugged and foolproof, this board wont up and die on you in the middle of a project!
  • Available memory: ~5.25K bytes for use (2.75K taken for the bootloader)
  • Available in both 3V and 5V flavors
  • On-board 3.3V or 5.0V power regulator with 150mA output capability and ultra-low dropout.
  • Input Voltage: Up to 16V input
  • Reverse-polarity protection
  • Thermal Shutdown
  • 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.
  • 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!
