Like the Trinket, it has onboard USB bootloading support – we opted for a MicroUSB jack this time.
ADAFRUIT TRINKET PINS PRO
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. Reset button for entering the bootloader or restarting the program.Pro Trinket is a whole new version of the older Trinket containing the AT mega 328P chip just like the Arduino UNO board.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 3.3V 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.Has headers for an FTDI port for reprogramming.USB bootloader so you can program it with AVRdude and/or the Arduino IDE (with a few simple config modifications).ATmega328P onboad chip in QFN package running at 3.3V logic.

The bootloader does not affect RAM usage.Īdafruit Pro Trinket - 3V 12MHz - Genel Özellikler The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28,672 bytes.
ADAFRUIT TRINKET PINS CODE
The USB connection is for uploading new code only.
ADAFRUIT TRINKET PINS SERIAL
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. There is no Serial-to-USB chip onboard.You cannot plug shields directly into the Pro Trinket.The onboard power supply is a 3.3V regulator and it can provide 150mA output.The NeoPixel Library works fine at 12MHz. Only the most timing-specific libraries may be affected, check the documentation. Adafruit Pro Trinket - 3V 12MHz runs at 12MHz, this doesn't affect most projects.Pins #2 and #7 are not available (they are exclusively for USB).Here are some things you may have to consider when adapting Arduino sketches: Adafruit Pro Trinket - 3V 12MHz is programmable using the Arduino IDE as you already set up, and 95% of Arduino projects will work out of the box! However, it uses 3V logic and 12MHz clock which means it's good when you want a lower-power and lower-voltage setup. It also has Optiboot support, so you can either program your Adafruit Pro Trinket - 3V 12MHz over USB or with a FTDI cable just like the Pro Mini and friends.Īdafruit Pro Trinket - 3V 12MHz uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. Like the Trinket, Adafruit Pro Trinket - 3V 12MHz has onboard USB bootloading support and a MicroUSB jack. It has 18 GPIO, 2 extra analog inputs, 28K flash and 2K of RAM. Adafruit Pro Trinket - 3V 12MHz designed for projects in which users need more pins, more flash and more RAM.
