Microduino- CoreSTM32

Microduino-CoreSTM32 is one of core modules of Microduino series, Microduino-CoreSTM32 is an open source hardware . 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.


  • Small, stackable, and ecomomic
  • Open source hardware circuit design and Arduino compatible programming development environment.
  • Using the U-Shape 27-pin interface (UPin-27)--the standard interface of Microduino series
  • Microduino- CoreSTM32 can work with Microduino-USBTTL and burn programs into the bootloader flexibly.
  • With a uniform Microduino interface standard and rich peripheral modules, it can easily connect with other Microduino modules and sensors.
  • 2.54mm (0.1 inch) pin pitch, compatible with bread boards and pegboards.
  • Microduino- CoreSTM32 can work with Microduino-USBTTL and burn programs into the bootloader flexibly.

Microduino- CoreSTM32 used components.


Set up the Microduino-CoreSTM32 development environment

  • Use the Maple IDE development environment: Microduino use the similar development environment with the Arduino IDE, so you can use the Maple IDE, Flash or Processing and so on. Combine with other Microduino module, you can finish more interesting projects.
  • Download the program to Microduino-CoreSTM32, you must use the Microduino-USB2TTL 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
