Description
The Trinket is 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. Adafruit 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 Adafruit 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. 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.
Trinket does not have a Serial port connection for debugging so the serial port monitor will not be able to send/receive data
- 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)
- Power with either USB or external output (such as a battery)
- On-board green power LED and red pin #1 LED
- Reset button for entering the bootloader or restarting the program
- 5x GPIO
- Hardware I2C / SPI capability for breakout & sensor interfacing.
- Mounting holes
