프로 트린켓 3V 12Mhz -작은 크기의 아두이노 우노
(Adafruit Pro Trinket - 3V 12MHz)
개요
- 본 제품은 Pro Trinket 3V입니다.
- Pro Trinket은 Trinket 보드와 아두이노 ATmega328 칩의 장점을 결합한 제품으로 아두이노 프로 미니와 비슷하지만 좀더 많은 핀을 가지고 있으며, USB 커넥터가 장착되어 있습니다.
- 좀더 많은 18개의 GPIO, 2개의 추가 아날로그 입력, 28K의 플래쉬, 2K의 램을 가지고 있습니다.
- Trinket과 마찬가지고 USB 부트로딩을 지원하여 USB 케이블을 이용하여 프로그래밍이 가능합니다.
- 크기는 작지만 아두이노 우노와 동일한 기능을 가지고 있어, 아두이노 우노를 이용하여 프로토타이핑 한 프로젝트의 크기를 줄이고 싶다면 본 제품은 훌륭한 선택이 될 것입니다.
- Pro Trinket 3V는 3V 로직과 12Mhz 클럭을 사용하기 때문에, 저전력 저전압용으로 사용하기 좋습니다.
- 아두이노 IDE를 통해 프로그래밍이 가능합니다.

특징
-
Here's some handy specifications:
- ATmega328P onboad chip in QFN package running at 3.3V logic
- 12MHz 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 3.3V 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!
- 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 Pro Trinket 3V runs at 12MHz, this doesn't affect most projects. Only the most timing-specific libraries may be affected, check the documentation! The NeoPixel Library works fine at 12MHz.
- The onboard power supply is a 3.3V regulator and it can provide 150mA output
- 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.
- Dimensions:
- 38mm x 18mm x 2mm / 1.5" x 0.7" x 0.08"
- Height with MicroUSB: 4mm / 0.16"
- Weight: 2.6g
