ATtiny85 on-board, 8K of flash, 512 byte of SRAM, 512 bytes of EEPROM. Simply use a USB v2 port or a USB hub in between. Some computers' USB v3 ports don't recognize the Trinket's bootloader. Adafruit trinket gpio serial#
Trinket does not have a Serial port connection for debugging so the serial port monitor will not be able to send/receive data.
There are some things you trade off for such a small and low cost microcontroller! It can run at 8 MHz or at 16MHz by setting the software-set clock frequency.Įven though you can program Trinket using the Arduino IDE, it's not a fully 100% Arduino-compatible. You can't stack a big shield on it but for many small & simple projects the Trinket will be your go-to platform. After some simple modifications to the Arduino IDE, it works like a mini-Arduino board. Uses a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino. 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. It's our lowest-cost arduino-IDE programmable board! 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 a microcontroller board that is small enough to fit into any project, and low cost enough to use without hesitation.
Works with many basic Arduino libraries including Adafruit Neopixel!ĭimensions: 1.2" x 0.6" x 0.2" / 31mm x 15.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. Hardware I2C / SPI capability for breakout & sensor interfacing. 
The 2 shared IO pins have 2 more analog inputs and one more PWM output. The 3 independent IO pins have 1 analog input and 2 PWM output as well.
5 GPIO - 2 shared with the USB interface. Reset button for entering the bootloader or restarting the program. On-board green power LED and red pin #1 LED. Power with either USB or external output (such as a battery) - it'll automatically switch over. On-board 3.3V or 5.0V power regulator with 150mA output capability and ultra-low dropout. Available memory: ~5.25K bytes for use (2.75K taken for the bootloader). Bootloader is rugged and foolproof, this board wont up and die on you in the middle of a project!. Micro-USB jack for power and/or USB data uploading. Oscillator frequency: 8MHz 3V, 8Mhz 5V, 16Mhz 5V. Memory: 8K of flash, 512 byte of SRAM, 512 bytes of EEPROM. Simply use a USB v2 port or a USB hub in between Trinket does not have a Serial port connection for debugging so the serial port monitor will not be able to send/receive data. Even though you can program Trinket using the Arduino IDE, it's not a fully 100% Arduino-compatible. Both work the same, but have different operating logic voltages.The 3V version should only run at 8 MHz, whereas the 5V version can run at 8 MHz or at 16MHz by setting the software-set clock frequency. There are two versions of the Trinket boards available, One is 3V and one is 5V. Its comes with USB bootloader, so you can plug it into any computer and reprogram it over a USB port just like an Arduino. Its a low cost, small size board, perfect for when you don't want to use your expensive development board,it's lowest-cost arduino-IDE programmable board.Its comes with 8K flash memory and has 5 GPIO pins, including analog inputs and PWM outputs. Trinket is a tiny microcontroller board, built around Atmel ATtiny85 IC, a little chip with a lot of power.
