Project Introduction:

Dianchuangpai is a development board based on the Liangshanpai (梁山派) development board in terms of functionality and appearance. To improve performance and user experience, some modifications and upgrades have been made to the Liangshanpai. Compared to Liangshanpai, Dianchuangpai uses the more advanced STM32F103ZET6 as the main controller and exposes all pins, enabling more flexible development and application.
For ease of use and debugging, Dianchuangpai V20 adds a full-color LCD screen for information display, showing the current system status in real time. Simultaneously, during program burning, Dianchuangpai uses the efficient and reliable DAP-Link burning method, resulting in faster and more stable burning speeds.
Dianchuangpai not only retains the original sensor interfaces and integrated circuits of Liangshanpai but also boasts more powerful processing capabilities and richer expansion interfaces, meeting a wider range of application needs. Therefore, Dianchuangpai is a high-performance development board suitable for a wide range of educational, research, and maker projects.
The name "Electronic Innovation School" comes from the fact that my club is called the Electronic Skills Innovation Association, abbreviated as "Electronic Innovation." To contribute to the club before leaving school, and because one of our club's major competitions used the STM32F103ZET6 chip, I designed the Electronic Innovation School for club members to use in various competitions and for learning.

 
Schematic Design:
1. Power Supply Circuit: A port of the Liangshan School DC-DC step-down circuit, using the TMI3411 chip, 5V input, 3V3 output.
 
2. Main Control Chip: Unlike the Liangshan School's GD32F470ZGT6, the Electronic Innovation School uses the STM32F103ZET6. The crystal oscillator circuit and BOOT selection are similar.
 
3. Peripheral Circuits: For ease of use and debugging, the Electronic Innovation School adds a full-color LCD screen for information display.
 
 
4. Download Interface----------- Similar to Liangshanpai, Dianchuangpai uses the efficient and reliable DAP-Link programming method for faster and more stable programming. Due to limited board space, all resistors and capacitors
 
 
 
in the PCB design
are 0402 packages. Similar to Liangshanpai, 6mil traces are used. The DAP-Link included with Liangshanpai
 
cannot be directly used with Dianchuangpai. It is suspected that the STM32 chip firmware needs to be reprogrammed into the DAP-Link of Liangshanpai before it can be used for programming Dianchuangpai. To solve the programming problem, I chose CW- link from Chuangxin Workshop to implement the DAP programming method for Dianchuangpai. For a clearer view, please carefully examine the differences between Liangshanpai, Dianchuangpai V10, and Dianchuangpai V20.
