•ATtiny 85 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 USBtiny ISP so you can program it with AVRdude and/or the Arduino IDE• Mini-USB jack for power and/or USB (Universal Serial Bus) uploading, you can put it in a box or tape it up & use any USB (Universal Serial Bus) cable for when you want to reprogram• We really worked hard on the boot-loader process to make it rugged & foolproof, this board wont up & 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 150m A output capability & ultra-low dropout• Up to 16V input, reverse-polarity protection, thermal & current-limit protection• Power with either USB (Universal Serial Bus) or external output (such as a battery)
- it'll automatically switch over• On-board green power LED & 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 (Universal Serial Bus) interface• The 3 independent IO pins have 1 analogue input & 2 PWM output as well• The 2 shared IO pins have 2 more analogue inputs & one more PWM output• Hardware I2C / SPI capability for breakout & sensor interfacing• Mounting holes! Yeah!• Really really small!• Please Click here for the detailed tutorial guide Trinket may be small, but do not be fooled by its size! It's a tiny microcontroller board, built around the Atmel ATtiny 85, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project, & low cost enough to use without hesitation. Perfect for when you don't want to give up your expensive dev-board & 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 Attiny 85 is a fun processor because despite being so small, it has 8K of flash, & 5 I/O pins, including analogue inputs & PWM 'analogue' outputs. We designed a USB (Universal Serial Bus) boot loader so you can plug it into any computer & reprogram it over a USB (Universal Serial Bus) 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 & one is 5V. Both work the same, but have different operating logic voltages. Use the 3V one to interface with sensors & devices that need 3V logic, or when you want to power it off of a Li Po battery. The 3V version should only run at 8 MHz. Use the 5V one for sensors & components that can use or require 5V logic. The 5V version can run at 8 MHz or at 16 M Hz 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 & 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 (Universal Serial Bus) v 3 ports don't recognize the Trinket's boot loader. Simply use a USB (Universal Serial Bus) v 2 port or a USB (Universal Serial Bus) hub in between• Trinket is not supported on Linux operating system at this time
