'''[[Microduino-CoreSTM32]]''' is one of core modules of Microduino series, '''[[Microduino-CoreSTM32]]''' is an open source hardware and [http://leaflabs.com/docs/hardware/maple-mini.html Maple Mini]  compatible. It is an 32-bit ARM Cortex-M3 development board, based on STMicroelectronics' STM32F103CBT6 chip.


==Features==
* Small, Stackable, Strong
* Open source hardware, using the same development environment as Arduino IDE 
* Using the U-Shape 27-pin interface (UPin-27), the standard interface of Microduino series

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

==Specifications==
* Microcontroller: STM32F103CBT6
* Speed: 72MHz
* Operating Voltage: 5V
* Core Voltage: 3.3V
* Flash: 128KB
* SRAM:  20KB
* Digital I/O Pins: 14 (of which 6 provide PWM output with D3，D5，D6，D9，D10 and D11)
* Analog Input Pins: 8 (2 more comparing to Arduino Uno)
* DC Current per I/O Pin: 40 mA
* DC Current:  50 mA
* Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data.
* External Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. See the attachInterrupt() function for details.
* PWM: 3, 5, 6, 9, 10, and 11. Provide 8-bit PWM output with the analogWrite() function.
* SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication using the SPI 

library.
* TWI: A4 or SDA pin and A5 or SCL pin. Support TWI communication using the Wire library.
* AREF. Reference voltage for the analog inputs. Used with analogReference().
* Flash Memory	32 KB (ATmega328P) of which 0.5 KB used by bootloader
* SRAM	2 KB (ATmega328P)
* EEPROM	1 KB (ATmega328P)
* Clock Speed	16MHz(5V) / 8Mhz(3.3V)

==Development==
* Microduino Arduino IDE Configuration
** 1. Install Arduino IDE: Microduino use the same IDE as Arduino, please download Arduino IDE from 【'''[http://arduino.cc/en/Main/Software Arduino IDE official]'''】 and install it in your disk. (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-hardware.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.
