Dysyx-QR STM32 Embedded Technology Experimental Platform

I. Overview

Based on the STM32 series of embedded chips, starting from the characteristics of embedded experimental teaching, the basic functional experimental circuit adopts an integrated design method, and the innovative and expanded experimental circuit adopts an independent module method, which can be connected to the m*nboard when necessary, taking into account both demonstration and verification experiments, and Consider the need for comprehensive design and innovative research experiments. The motherboard comes with a CPU programming download interface. It is a highly flexible new embedded experimental teaching platform that integrates programming, downloading and debugging. It is suitable for students at all levels to conduct experiments and innovations in embedded principles and applications.   

2. Characteristics

1. Complete experimental guidance

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

2. Function modules are completely independent

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

3. Support multiple CPU development experiments

The STM32F103C8T6 core board is standard, and other microcontroller core boards can be selected according to customer needs to expand support for various CPU chips.
