The Adafruit Trinket 5V is a tiny microcontroller board built around the Atmel ATtiny85 processor. At just 27mm × 15mm, it's small enough to fit into virtually any project and affordable enough to dedicate to a single build. Program it via the Arduino IDE over the Micro-USB connector — no separate programmer required.

This is the 5V version, designed for interfacing with 5V sensors, components, and logic levels. It can run at 8 MHz or 16 MHz via a software-configurable clock setting. For 3.3V logic or LiPo battery projects, choose the 3V version instead.

Key Features

  • ATtiny85 Processor – 8K flash (~5.25K usable), 512 bytes SRAM, 512 bytes EEPROM
  • 5 GPIO Pins – 3 independent I/O (1 analog input, 2 PWM outputs) plus 2 shared with USB (2 more analog inputs, 1 more PWM output)
  • Arduino IDE Compatible – USB bootloader allows programming directly from the Arduino IDE or AVRdude
  • Micro-USB Connector – For programming and power
  • Onboard 5.0V Regulator – 150mA output with up to 16V input, reverse-polarity protection, thermal and current-limit protection
  • Automatic Power Switching – Powers from USB or external source (battery), switches automatically
  • Hardware I2C / SPI – For connecting breakouts and sensors
  • 8 MHz or 16 MHz Operation – Software-configurable clock speed
  • Onboard LEDs – Green power LED and red LED on pin #1
  • Reset Button – Enter bootloader or restart without unplugging
  • Mounting Holes – For secure installation
Note: While programmable via the Arduino IDE, the Trinket is not fully Arduino-compatible. It does not support serial port monitoring, and some USB 3.0 ports may not recognise the bootloader — use a USB 2.0 port or hub if you experience issues.

Ideal For

  • Small, embedded projects with minimal I/O requirements
  • NeoPixel and LED projects
  • Wearable electronics and compact builds
  • Dedicated microcontroller for single-purpose 5V projects
