In fact we even made some simple modifications to the Arduino IDE so that it works like a mini-Arduino board. We designed a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino. It's our lowest-cost arduino-IDE programmable board!Īs of May 27th, 2015 the 3.3V Trinket has been revised! The board is now even smaller - at just 27mm x 15mm - and comes with a micro-B USB connector rather than mini-BThe 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. 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.
We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. 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. Once headers are installed they can be fitted into 0.6" wide sockets Works with 99% of existing Arduino sketches (anything that doesn't use more than 28K, and doesn't require pins #2 and #7) Reset button for entering the bootloader or restarting the program.
On-board green power LED and red pin #13 LED Power with either USB or external output (such as a battery) - it'll automatically switch over Up to 16V input, reverse-polarity protection, thermal and current-limit protection. On-board 5.0V power regulator with 150mA output capability and ultra-low dropout. 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. USB bootloader with a nice LED indicator looks just like a USBtinyISP so you can program it with AVRdude and/or the Arduino IDE (with a few simple config modifications).Īlso has headers for an FTDI port for reprogramming The bootloader does not affect RAM usage.

The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28,672 bytes.

The USB connection is for uploading new code only.

This is to keep the Pro Trinket small and inexpensive, you can use any FTDI cable to connect to the FTDI port for a Serial connection. You cannot plug shields directly into the Pro Trinket The onboard 5V regulator can provide 150mA output, not 800mA out Pins #2 and #7 are not available (they are exclusively for USB) Here's some things you may have to consider when adapting Arduino sketches: So you'll be happy to hear that not only is Pro Trinket programmable using the Arduino IDE as you already set up, but 99% of Arduino projects will work out of the box!įor tons more details, check out the Introducing Pro Trinket tutorial The Pro Trinket 5V uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. So it's great once you've finished up a prototype on an official Arduino UNO and want to make the project smaller. The Pro Trinket PCB measures only 1.5" x 0.7" x 0.2" (without headers) but packs much of the same capability as an Arduino UNO. We also added Optiboot support, so you can either program your Pro Trinket over USB or with a FTDI cable just like the Pro Mini and friends. Like the Trinket, it has onboard USB bootloading support - we opted for a MicroUSB jack this time. That's why we designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM. Trinket's a year old now, and while its been great to see tons of tiny projects, sometimes you just need more pins, more FLASH, and more RAM.
It's like an Arduino Pro Mini with more pins and USB tossed in, so delicious. Trinket's got a big sister in town - the Pro Trinket 5V! Pro Trinket combines everything you love about Trinket with the familiarity of the common core Arduino chip, the ATmega328. All have built-in USB and are comparable in price! The ItsyBitsy's especially are about the same size and have native USB and tons of pins, so they're a very close compatible. So while we still carry the Pro Trinket, we really recommend using the Metro Mini (ATmega328 5V 16 MHz), ItsyBitsy 32u4 5V 16MHz, ItsyBitsy 32u4 3.3V 8MHz or ItsyBitsy M0 3V 48MHz. We still love the Pro Trinket but the bit-bang USB technique it uses doesn't work as well as it did in 2014.
