Product Description ------------------- Adafruit Trinket Mini Microcontroller is a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. It's 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. Adafruit 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 and simple projects the Trinket will be your go-to platform. This is the 3V Trinket. 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. 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. It's specifications are 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. 5.25K bytes available for use (2.75K taken for the boot-loader). On-board 3.3V power regulator with 150 mA 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. The 2 shared IO pins have 2 more analog inputs and one more PWM output. Box Contains ------------ 1x 3.3V Trinket
