Adafruit PRO Trinket - 5V 16MHz

The 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 analogue inputs and PWM ' analogue' 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. Features: ATtiny85 on-board, 8K of flash, 512 bytes 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) 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. We really worked hard on the bootloader process to make it rugged and foolproof, this board won't up and die on you in the middle of a project! ~5.25K bytes available for use (2.75K taken for the bootloader) Package Includes: 1 x Adafruit Pro Trinket - 5V 16MHz
