Microduino-Core 마이크로두이노 코어모듈는 마이크로두이노 시리즈 코어 모듈중에 하나이다. 마이크로두이노 코어모듈는 아두이노 우노(UNO) 보드와 호환되는 오픈 소스 하드웨어이다. Atmel사의 ATmega328P/ATmega168PA 시리즈를 기반으로 한 8비트 마이크로컨트롤러 개발보드이다. 아두이노 우노보드와 비교해 보면, 마이크로두이노 코어모듈'의 특징은 아래와 같다. 아두이노 우노보드를 마이크로컨트롤러 부분인 마이크로두이노 코어모듈와 USB2TTL 부분인마이크로두이노-FT232R 모듈로 분리했다. 마이크로두이노 코어모듈'에 프로그램을 업로딩 하고 난 후 Microduino-FT232R모듈은 항상 필요없으므로 마이크로두이노 코어/코어 플러스 모듈이 여러개여도 Microduino-FT232R모듈은 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, 마이크로두이노 코어모듈은 4개 다른 구성을 가지고 있다.

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.

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.

Features Small, Stack, Strong Open source hardware, using the same development environment as Arduino IDE Microduino-Core can be burned with ISP, same as Arduino, easy "bootloader" Using the U-Shape 27-pin interface (UPin-27), the standard interface of Microduino, all Microduino modules and sensors can be easily stacked and extended through it Delivered ready to plug in. 2.54mm (0.1 inch) pin pitch, compatible to bread board and hole board
