DYSYX-QR STM32 Embedded Technology Training Platform

I. Overview

Based on the STM32 series embedded chips and the characteristics of embedded experimental teaching, the basic functional experimental circuit adopts an integrated design method, and the innovative expansion experimental circuit adopts an independent module method, which is connected to the m*nboard when needed, taking into account both demonstration and verification experiments and the needs of comprehensive design and innovative research experiments. The m*nboard has a built-in CPU programming and download interface, which is a highly flexible new embedded experimental teaching platform that integrates programming, downloading and debugging, and is suitable for students at all levels to conduct experiments and innovations in embedded principles and applications.   

2. Features

1. Complete experimental guidance

A det*led experimental instruction book is specially prepared for this experimental box. I believe that with a professional experimental box and a det*led instruction book, you will quickly master the ARM embedded technology, get started quickly, and achieve twice the result with half the effort.

2. Functional modules are completely independent

Based on our years of development experience and the suggestions of users, this development board adopts the latest concept - each functional module is completely independent and does not interfere with each other, reducing programming errors for beginners. The board is equipped with rich experimental hardware resources and interfaces, and all I/O ports are open to the outside world. You can simply use the short-circuit cap to connect the default resources (convenient for beginners to use directly), or you can remove the short-circuit cap and use the DuPont line to connect any I/O port line of the microcontroller to easily build your own circuit. With a large number of C language experimental routines carefully written by our company, users can quickly master the principles of microcontrollers and their practical interface technology. At the same time, it can enhance beginners' understanding of the motherboard hardware circuit and familiarize themselves with the hardware circuit as soon as possible.

3. Support multiple CPU development experiments

The standard STM32F103C8T6 core board can be equipped with other MCU core boards according to customer needs, so as to achieve support expansion for various CPU chips.
