Description: Adafruit Trinket - Attiny85 mini module - 3.3V
Miniature module with an AVR Attiny85 microcontroller and is equipped with 8 KB of Flash memory, 5 digital pins, analog input and 2 PWM channels. On board is miniUSB connector, through which the system can be programmed via the Arduino IDE using thecable. After onlya few minor changes, the board behaves like a standardArduino.
The presentation of the Adafruit Trinket board's possibilities.
Choose the right board
In our offer, you will find two versions of the Adafruit Trinket -3.3 Vand5.0 V. Both modules work in the same way, differing only in the operating voltage of the logic leads and maximum clock frequency. The 3.3 V version runs at a frequency of 8 MHz, 5.0 V and works with 8 MHz and 16 MHz.

The collaboration with Arduino
The device can be programmed via the Arduino environment, however, due to the small size of the board, there are some differences:
- Trinket has no serial port and the serial monitor embedded in the environment of Arduino, will not work.
- Computers equipped with USB 3.0 ports can have a problem with the recognition of the Trinket bootloader, the solution to this situation is to use an external USB 2.0 hub.
- The board is working with Windows and Mac OS, at the moment, there are no drivers for Linux.
