## Overview

The Adafruit Trinket 5V is a minimalist microcontroller board built around the ATtiny85 chip, featuring 8K flash memory, 512 bytes each of SRAM and EEPROM, and an 8MHz internal oscillator (expandable to 16MHz). It includes a USB bootloader for easy programming via Micro-USB, an onboard 5V regulator with multiple protections, and a compact design perfect for embedding in small-scale projects. Ideal for makers and professionals seeking a low-cost, versatile microcontroller that fits anywhere without sacrificing power.

## Description

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. We 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 our 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. We 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 we 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. This is the 5V Trinket. There are two versions of the Trinket. One is 3V and one is 5V. Both work the same, but have different operating logic voltages. Use the 3V one to interface with sensors and devices that need 3V logic, or when you want to power it off of a LiPo battery. The 3V version should only run at 8 MHz. Use the 5V one for sensors and components that can use or require 5V logic. 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. 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

Review: Great little arduino controller with so many uses for so little money - GREAT price for a TINY controller capable of so much! First let me say for all of you who had trouble with this thing go check out these GREAT directions from adafruit: https://learn.adafruit.com/introducing-trinket/setting-up-with-arduino-ide BE CLEAR when setting up the arduino IDE board type in Tools, you are working on a TRINKET 5V with this item. NOT a PRO Trinket. Secondly, yes you have to push the hardware reset button to get in to bootloader mode and upload a sketch, that is different from a regular arduino but easily doable and they provide a PIN to solder a wire to and make a remote reset button if needed. There IS a signed driver for windows 8 and a driver for Windows 7 from adafruit: https://learn.adafruit.com/usbtinyisp/drivers I just got this today, messed with it for a bit, downloaded the win8 signed driver from the above link. I added the hardware info folder from the downloaded zip file in to my documents\arduino (where your sketches are saved) folder as described in the top link. Then I added the avrdude.conf from the top instructions link to my IDE path again as described in the directions. Chose the board and CHANGE PROGRAMMER to USBTinyISP in Tools menu and you are Good to Go. They talk about using the BLINK demo to test an upload. The pin in the default blink demo for the LED is 13 but you need to change it to 1 to get this LED to blink. So absolutely tiny for so many awesome users. I plan on using it with PIR detectors and a set of quad relays to trigger my Halloween decorations next year when someone is actually present rather than the crappy light sensors they use that hardly ever work! If you want out of the box plug and play then you may not like it but if you are familiar with pointing windows to the downloaded drivers folder when you plug it in and you don't mind adding some files to the arduino IDE then this should do just fine for you!
Review: Great tiny micro-controller - sips power, delivers excellent performance - This was a great, fast buy. I needed one of the trinkets fast to help with a local high school tech club project. In particular these do a great job of driving the adafruit neo pixels, driving LEDs, reading button presses and other small tasks that you may need to quick and simple projects. It is amazing that this thing will run well on a tiny LiPo battery. Bear in mind that the 'serial port' is not a serial port: once you get the computer all ready, and then you push the button on the trinket to get the red light flashing *just before* you download the code. Only then will the trinket "wake up and pay attention" to the computer sending the programming down the line. All of this is covered in the manual, but it is worth repeating to prevent disappointment/frustration.

## Features

- ATtiny85 on-board, 8K of flash, 512 byte of SRAM, 512 bytes of EEPROM 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.
- ~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.

### ⭐⭐⭐⭐⭐ Very useful board.
*by E***T on May 31, 2017*

These are great little arduino boards. I was able to create a custom count down clock with an attached piezo buzzer very easily and run it off of a cell phone booster battery. Note to the people saying that these don't work, they do require about 10 minutes of special set up. These don't have a serial programmer built in and much be programmed directly via USB. You will need to install the custom boards via a URL in your preferences and also install the special custom programmer. then, you have to push the button on the board before writing to it. You should check out the adafruit website for instructions. This is the 5V version of the board (there is also a 3.3V version). It can run at 8 mhz or 16 mhz depending on which board you pick in the arduino IDE
