'''[[Microduino-Core+]]''' 는 '''[www.atmel.com Atmel]'''사의 ATmega644PA/ATmega1284P 시리즈를 메인칩으로 사용하고 있습니다. '''[[Microduino-Core|마이크로두이노 코어]]'''버전보다 성능이 향상된 모듈입니다..

'''[[Microduino-Core+]]''' has all features of –Core, can be stacked with modules through UPin-27 Microduino standard bus interface, as smart as '''[http://arduino.cc/en/Main/ArduinoBoardMega2560 Arduino Mega2560]''', but as small as a quarter. Moreover, '''[[Microduino-Core+]]''' has 10 more digital I/O ports than '''[[Microduino-Core]]''', provides 2 hardware serial ports, and more SRAM/Flash/EEPROM, it’s designed for high hardware resource required applications and designs. 

'''[[Microduino-Core+|마이크로두이노 코어 플러스]]'''는 마이크로두이노 코어의 모든 기능을 가지고 있으며 UPin-27 마이크로두이노 기본 인터페이스를 이용해서 쌓아 올릴수 있다. '''[http://arduino.cc/en/Main/ArduinoBoardMega2560 Arduino Mega2560]'''보드 만큼 스마트하지만 사이즈는 1/4정도 작습니다.

Microduino uses the same development environment as Arduino IDE, designers can use the Arduino IDE, Processing on Microduino for idea realization, prototype development and low volume production. Programs can be smoothly migrated from Core to Core+ without any modification. 

Microduino uses optiboot for bootloader, it takes less Flash than Arduino default engine and optimizes program uploading.

Currently, there are 4 different configurations for '''[[Microduino-Core+]]''' modules:

Different configurations in frequency and supply voltage:
* Clock frequency and supply voltage are paired; 8M module is supplied by 3.3V voltage, while 16M module is by 5.0V voltage. 
* A 16M with 5V '''[[Microduino-Core+]]''' module is recommended for desktop equipments or designs; regarding mobile equipments or designs, a 8M with 3.3V module is suggested for low power and battery supply purposes.

==Core vs Core+==
*  '''[[Microduino-Core+]]''' aims at high performance applications which require large SRAM/EEPROM/Flash and more I/O ports, '''[[Microduino-Core]]''' is for main stream applications.

* 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.

(if you already have it, just skip this step). Please check Arduino IDE details from 【'''[http://arduino.cc/en/Reference/HomePage Reference]'''】 and 【'''[http://arduino.cc/en/Tutorial/HomePage Workshop]'''】. 
** 2. Patch Microduino package: Please download Microduino package for Arduino IDE from 【'''[[media:Microduino.zip|download]]'''】, and unzip is to {Your Arduino Install Driectory}/hardware directory.
** Microduino Arduino IDE Reference workshop: 【'''[[Arduino IDE Microduino Configuration]]'''】. 
** 3. Programming: To upload program to Microduino-Core/Core+ through Arduino IDE, designers are recommended to use '''[[Microduino-FT232R]]''' module.
** 4. Enjoy your Microduino journey!

* Burn Microduino BootLoader
** Bootloader burning is necessary if designers want to update Microduino-Core/Core+ firmware by themselves, designers can leaverage Arduino Uno or another burned Microduino-Core/Core+ to make a new one.
** Microduino bootloader workshop: 【'''[[Burn Bootloader to Microduino-Core/Core+ with an Arduino]]'''】.
** Bootloader is specified for different Microduino-Core/Core+ configurations, correct one must be selected during burning.
** Initial bootloader is designed for ATmegaX8 series optiboot, which occupies only 512 bytes flash.
