Microduino- CoreSTM32

Microduino-CoreSTM32 is one of the core modules of Microduino, adopting ARM development board of STM32F103CBT6 chip. Microduino-CoreSTM32 is a open-source software, compatible with Maple Mini, and it can be used together with Microduino extension modules and other electronic components, modules, and sensors to make many funny interactive works.


  • Small, cheap, stackable, and open;
  • Open source hardware circuit design and programming development environment similar to Arduino.
  • Microduino-CoreSTM32 can work with Microduino-USBTTL and burn programs into the bootloader flexibly.
  • With an uniform Microduino interface standard and rich peripheral modules, it can be easily connected with other Microduino modules and sensors.
  • 2.54mm-spacing female connector interface,which makes it easy to integrate to the pegboard.

Set up the Microduino-CoreSTM32 development environment(1)

  • 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. Combining with other Microduino modules, you can make many interesting interactive works..
  • Configure the Maple IDE, please refer to Microduino-CoreSTM32 Maple Drive Install
  • TO download programs to Microduino-CoreSTM32, just use the USB interface of Microduino-CoreSTM32, without Microduino-USBTTL, which is only used when programming bootLoader. There is bootloader, by default, so you don't have to program it.

Program for Microduino-CoreSTM32

  • Make sure installed the Microduino-CoreSTM32 derive
  • Prepared hardware:Microduino-CoreSTM32, USB cable
  • Prepared software:Maple IDE
