'''[[Microduino-Core/ko|마이크로두이노 코어모듈]]'''는 마이크로두이노 시리즈 코어 모듈중에 하나이다. '''[[Microduino-Core/ko|마이크로두이노 코어모듈]]'''는 아두이노 우노(UNO) 보드와 호환되는 오픈 소스 하드웨어이다. [http://www.atmel.com Atmel]사의 ATmega328P/ATmega168PA 시리즈를 기반으로 한 8비트 마이크로컨트롤러 개발보드이다.
아두이노 우노보드와 비교해 보면, '''[[Microduino-Core/ko|마이크로두이노 코어모듈]]''''의 특징은 아래와 같다.


*'''[http://arduino.cc/en/Main/ArduinoBoardUno 아두이노 우노보드]'''를 마이크로컨트롤러 부분인 '''[[Microduino-Core/ko|마이크로두이노 코어모듈]]'''와 USB2TTL 부분인'''[[마이크로두이노-FT232R 모듈]]'''로 분리했다. '''[[Microduino-Core/ko|마이크로두이노 코어모듈]]''''에 프로그램을 업로딩 하고 난 후 '''[[Microduino-FT232R]]'''모듈은 항상 필요없으므로 마이크로두이노 코어/코어 플러스 모듈이 여러개여도 '''[[Microduino-FT232R]]'''모듈은 하나만 가지고 있어도 된다. 보드사이즈는 사각형으로 25.4mm X 27.94mm로 매우 작다. 

* 마이크로두이노는 'U'자 모양의 27핀 인터페이스를 사용한다(UPin-27). 모든 마이크로두이노 코어 모듈, 확장 모듈, 확장 보드는 동일한 인터페이스를 사용하기 때문에 간단하게 연결해서 사용할 수 있다. 

* 작은 사이즈와 일정한 인터페이스를 가지고 있으므로, 마이크로두이노는 시제품의 가격과 사이즈를 획기적으로 줄인다. 아두이노 호환보드이므로 사용자의 경험을 유용성과 사용성을 확대한다.

마이크로두이노는 아두이노와 동일한 개발환경을 사용하고 있고, 아두이노 IDE, 프로세싱을 이용하여 아이디어를 현실화하고 시제품을 개발하고 소량생산 할 수 있다.

마이크로두이노는 optiboot 부트로더를 사용하고 있으므로 아두이노 디폴트 엔진보다 작은 메모리를 사용하여 프로그램 업로딩을 최적화했다.

현재, '''[[Microduino-Core/ko|마이크로두이노 코어모듈]]'''은 4개 다른 구성을 가지고 있다.

주파수와 공급전원의 설정:
* 동작주파수와 공급전원이 연계되어 있는데, 8MHz 동작 모듈은 3.3V를 공급받고, 16MHz 동작 모듈은 5.0V를 공급받는다.
* 16MHz/5.0V '''[[Microduino-Core/ko|마이크로두이노 코어모듈]]'''은 데스크탑 장비나 디자인에 이용하고, 8MHz/3.3V '''[[Microduino-Core/ko | 마이크로두이노 코어모듈]]'''은 저전력 배터리 전원공급이 가능한 모바일 디바이스를 설계하는데 사용할 것을 권장한다.

==Core vs Core+==
* Microduino also provides '''[[Microduino-Core+]]''' module, aiming at high performance applications which require large SRAM/EEPROM/Flash and more I/O ports.

* Both '''[[Microduino-Core]]''' and '''[[Microduino-Core+]]''' use UPin-27 interface -- the standard module interface of Microduino series. The main difference between them is MCU chip: -Core module uses ATmega328P/ATmega168PA, as same as Arduino Uno; -Core+ module uses ATmega644PA/ATmega1284P, its performance is similar to Arduino Mega2560.

* Configuration difference between '''[[Microduino-Core]]''' and '''[[Microduino-Core+]]'''

* According above table, Core and Core+ are different in Flash, EEPROM and SRAM size, also, they supply different size of digital I/O and hardware serial ports, and there are 10 more digital I/O and 1 more hardware serial ports in Core+. Designers can select specific module regarding different application requirements on function, performance and power. 

* Both Core and Core+ use UPin-27 interface, Microduino program can be smoothly ported between them.
