## Description

The Adafruit Trinket 3V3 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 3.3V version, designed for interfacing with 3.3V sensors and components or powering from a LiPo battery. The 3V Trinket runs at 8 MHz. For 5V logic or 16 MHz operation, choose the 5V 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 3.3V 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 Internal Oscillator – Can be doubled to 16 MHz in software 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 Wearable electronics and compact builds Battery-powered projects using 3.3V logic Dedicated microcontroller for single-purpose projects Package Contents 1× Adafruit Trinket 3V3 Microcontroller Board Resources Introducing Trinket Learning Guide Arduino IDE Programming Guide & Library Compatibility
