{"title":"Adafruit Trinket - 5V","handle":"adafruit-trinket-5v","url":"/products/adafruit-trinket-5v","description":"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.\n\nThis 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.\n\nKey Features\n\n\nATtiny85 Processor – 8K flash (~5.25K usable), 512 bytes SRAM, 512 bytes EEPROM\n\n5 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)\n\nArduino IDE Compatible – USB bootloader allows programming directly from the Arduino IDE or AVRdude\n\nMicro-USB Connector – For programming and power\n\nOnboard 5.0V Regulator – 150mA output with up to 16V input, reverse-polarity protection, thermal and current-limit protection\n\nAutomatic Power Switching – Powers from USB or external source (battery), switches automatically\n\nHardware I2C / SPI – For connecting breakouts and sensors\n\n8 MHz or 16 MHz Operation – Software-configurable clock speed\n\nOnboard LEDs – Green power LED and red LED on pin #1\n\nReset Button – Enter bootloader or restart without unplugging\n\nMounting Holes – For secure installation\n\n\n\nNote: 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.\n\n\nIdeal For\n\nSmall, embedded projects with minimal I/O requirements\nNeoPixel and LED projects\nWearable electronics and compact builds\nDedicated microcontroller for single-purpose 5V projects\n\n\nPackage Contents\n\n1× Adafruit Trinket 5V Microcontroller Board\n\n\nResources\n\nIntroducing Trinket Learning Guide\nArduino IDE Programming Guide & Library Compatibility\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":8020,"title":"Default Title","sku":"AF-1501","price":13.55,"on_sale":false,"in_stock":true,"available_quantity":110,"option1":"Default Title"}]}
