Adafruit 5V Logic Mini Microcontroller Trinket

Adafruit Logic Trinket is a tiny micro-controller board, built around the Atmel ATtiny85, a little chip with a lot of power.Use the 5V 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.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.A USB boot-loader is designed so you can plug it into any computer and reprogram it over a USB port just like an Arduino.In fact Adafruit has 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 and simple projects the Trinket will be your go-to platform.ATtiny85 on-board, 8K of flash, 512 byte of SRAM, 512 bytes of EEPROM.USB boot-loader with a nice LED indicator looks just like a USBtinyISP so you can program it with Argued(with a simple config modification) and/or the Arduino IDE (with a few simple config modifications).Mini-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.it is rugged and fool proof, this board wont up and die on you in the middle of a project.5.25K bytes available for use (2.75K taken for the boot-loader).On-board 3.3V or 5V power regulator with 150mA output capability and ultra-low dropout.Up to 16V input, reverse-polarity protection, thermal and 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 boot-loader or restarting the program.No need to unplug/replug the board every time you want to reset or update.5 GPIO - 2 shared with the USB interface.The 3 independent IO pins have 1 analog input and 2 PWM output as well
