Description

  • Tiny microcontroller board
  • Power with either USB or external output
  • Can run at 8 MHz or at 16MHz by setting the software-set clock frequency
  • On-board 5.0V power regulator with 150mA output capability and ultra-low dropout

The 5V Trinket Mini Microcontroller Board 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. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation.

  • 1.2" x 0.6" x 0.2" / 31mm x 15.5 x 5mm

Weight

  • (no headers): 1.85 grams
  • 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 looks just like a USBtinyISP so you can program it with AVRdude (with a simple config modification) and/or the Arduino IDE (with a few simple config modifications)
  • Micro-USB jack for power and/or USB uploading, you can put it in a box or tape it up and use any USB cable for when you want to reprogram.
  • On-board green power LED and red pin #1 LED
  • Reset button for entering the bootloader 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 interface. The 3 independent IO pins have 1 analog input and 2 PWM output as well. The 2 shared IO pins have 2 more analog inputs and one more PWM output.
  • Hardware I2C / SPI capability for breakout & sensor interfacing.
  • Works with many basic Arduino libraries including Adafruit Neopixel!
  • Really really small

Where size is at a premium

Excellent controller despite small size. My project is powered by USB so there was only 3 pins out of 5 available. Got around that problem by using a pair of 7447's. 16mhz software selectable. Excellent service and delivery as always from Robotshop!

Là où la taille est une prime

Excellent contrôleur malgré sa petite taille. Mon projet est alimenté par USB, il n'y avait donc que 3 broches sur 5 disponibles. Contourné ce problème en utilisant une paire de 7447. Logiciel 16 MHz sélectionnable. Excellent service et livraison comme toujours de Robotshop!

As advertised

What can I say? It does pretty much exactly what it says it does. Great for applications that require a small micro controller due to physical size restrictions. Still has a decent number of features despite size. The tab near the reset button does add an extra ~0.1" and doesn't seem to serve any purpose other than space to screen the device name on.

Comme annoncé

Que puis-je dire? Il fait à peu près exactement ce qu'il dit. Idéal pour les applications nécessitant un micro-contrôleur de petite taille en raison de restrictions de taille physique. A encore un nombre décent de fonctionnalités malgré la taille. L'onglet près du bouton de réinitialisation ajoute ~ 0.1 "supplémentaire et ne semble servir à rien d'autre que l'espace pour afficher le nom du périphérique.
