Itsy Bitsy 아두이노 호환 보드 -3V, 8Mhz, Atmega32u4
(Adafruit Itsy Bitsy 32u4 - 3V 8MHz)
개요
- 본 제품은 아두이노 호환 마이크로컨트롤러 Itsy 보드입니다.
- 컴팩트한 작은 크기지만 6 아날로그/디지털 핀, 17개 디지털 핀을 제공하고 있으며, 아두이노 우노나 피더 32u4와 같은 기능을 제공합니다.
- Itsy Bitsy 32u4 3V 8Mhz 보드는 Atmega32u4 칩을 탑재하고 있습니다.
- USB를 장착하고 있어 USB 시리얼 디버깅이 가능하며, 아두이노 IDE에서 개발이 가능합니다.
- 3V보드이지만 5V로직을 출력할 수 있는 핀(5번핀)을 하나 예비하여 놓았습니다.
특징
- ATmega32u4 onboad chip in QFN package
- 3.3V power and logic, 8 MHz clock rate, 2KB RAM and 28K FLASH
- USB bootloader with a nice LED indicator, AVR109 compatible (same as Flora, Feather 32u4, Leonardo, etc)
- Micro-USB jack for power, USB uploading and debugging, you can put it in a box or tape it up and use any Micro USB cable for when you want to reprogram.
- Can act as a USB HID Keyboard, Mouse, MIDI or plain USB 'CDC' serial device (default)
- On-board 3.3V power regulator with 500mA output capability and ultra-low dropout. Up to 6V input, reverse-polarity protection, thermal and current-limit protection.
- Special Vhigh output pin gives you the higher voltage from VBAT or VUSB, for driving NeoPixels, servos, and other high-current devices. Digital 5 level-shifted output for high-voltage logic level output.
- Power with either USB or external output (such as a battery) into VBAT pin - it'll automatically switch over
- On-board red pin #13 LED
- 23 GPIO total - 6 analog in, 1x SPI port, 1x I2C port, 1x Hardware Serial port and 10 more GPIO, 4 of which have PWM
- Can drive NeoPixels, connect to sensors, servos, etc.
- Reset button for entering the bootloader or restarting the program.
