The Pro Trinket is the Arduino Compatible solution for all of your small project needs.In stock + Adafruit Pro Trinket - 5V 16MHz quantity $9.95 USD- Add to cart SKU: 19037 Categories: Arduino-Compatible, Arduino-Compatible Modules, Brands Tag: allAccounts Description More Info Reviews (0) Description Say hello to Adafruit’s newest addition to the Trinket lineup, the Pro Trinket! Not only does is support the much loved ATmega328P, but also has a custom bootloader that gives you a handy USB interface. The Trinket Pro has a total of 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM. With all this capability packed into a form factor of only 1.5″ x 0.7″ x 0.2″ (without headers), you will be surprised how easy it is to migrate your project from an Uno down to the tiny Pro Trinket. Keep in mind that because of the Pro Trinket’s USB bootloader the flash storage (Arduino sketch size) is reduced to 28K instead of the Uno’s 31.5K. This should only be a problem if your pushing the absolute limit of the Uno’s flash memory when you got to make the switch over to the Pro Trinket. Here’s some things you may have to consider when adapting Arduino sketches: Pins #2 and #7 are not available (they are exclusively for USB) The onboard 5V regulator can provide 150mA output, not 800mA out You cannot plug shields directly into the Pro Trinket There is no Serial-to-USB chip onboard. 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. The USB connection is for uploading new code only. The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28,672 bytes. The bootloader does not affect RAM usage. Here’s some handy specifications: ATmega328P onboard chip in QFN package 16MHz clock rate, 28K FLASH available 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) Also has headers for an FTDI port for reprogramming 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 5.0V power regulator with 150mA output capability and ultra-low dropout. Up to 16V input, reverse-polarity protection, thermal and current-limit protection Power with either USB or external output (such as a battery) – it’ll automatically switch over On-board green power LED and red pin #13 LED Reset button for entering the bootloader or restarting the program. Works with 99% of existing Arduino sketches (anything that doesn’t use more than 28K, and doesn’t require pins #2 and #7) Mounting holes! Yeah!
