- Small enough to fit into any project, and low cost enough to use without hesitation.
- 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 & Micro-USB jack for power and/or USB uploading
- ~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.
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. 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!
It's fun processor because despite being so small, it has 8K of flash and 5 I/O pins, including analog inputs and PWM 'analog' outputs. Plug it into any computer and reprogram it over a USB port just like an Arduino. This trinket works like a mini-Arduino board although it's not a fully 100% Arduino-compatible. This 5V version can run at 8 MHz or at 16MHz by setting the software-set clock frequency designed for use with sensors and components that use or require 5V logic.
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
