'''[[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.
It can be combined with other Microduino modules and used in more projects.

==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
* 2.54mm (0.1 inch) pin pitch, compatible to bread board and hole board
* Microduino-CoreSTM32 can use the Microduino-USBTTL module to burn the bootloader. Refers to

==Development==
===Set up the Microduino-CoreSTM32 development environment===
* Use the Maple IDE development environment: Microduino use the similar developemnt environment with the Arduino IDE, so you can use the Maple IDE, Flash or Processing and so on. Conbine with other Microduino module, you can finish more interesting projects.
*Download the program to Microduino-CoreSTM32, you must use the [[Microduino-USB2TTL/zh]] module。
*Configure the Maple IDE, please refer to '''[[Microduino-CoreSTM32 Maple Drive Install]]'''

===Program for Microduino-CoreSTM32===

*Make sure installed the Microduino-CoreSTM32 derive
*Prepared hardware：Microduino-CoreSTM32、USB cable
*Prepared software：Maple IDE
'''[[The beginning of Micoduino-CoreSTM32]]'''

===Burn the Microduino- CoreSTM32  BootLoader===

*If you got a Microduino-CoreSTM32 board without the bootloader, you have to use the Microduino-CoreUSB to burn the bootloader firstly, please refers to '''[[Use the Microduino-USBTTL to burn bootloader for Microduino- CoreSTM32]]'''.
