ADAFRUIT PRO TRINKET 3V MCU Development Board 2010

Adafruit Pro Trinket Mini Microcontrollers

Adafruit Pro Trinket 5V development board Measures only 38 mm x 18 mm x 2 mm (1.5" x 0.7" x 0.2") (without headers) Provides easy and simple access to the ATtiny85 MCU for development and programming. Small form factor means it can easily be incorporated into prototype/ design.

The pro trinket features Microchip’s ATtiny85 MCU with 8KB program flash, 20 MIPS CPU, 5 PWMs, 2 8 bit timers. Uses the Atmel ATmega328P microcontroller, 28K of flash, 2K of RAM and 18 GPIO.


The Pro Trinket is programmable using the AVRdude and/or the Arduino IDE, and there is a reset button for entering the bootloader or restarting the program as well as LED indication for bootloading. You can also use an FTDI cable to connect to the FTDI port for a serial connection.

The Adafruit Pro Trinket development kit is the bigger, more powerful sister of the Trinket (RS 124-5509, 124-5506) with roughly 4 times the performance and GPIO.
