Based on the GD32F450ZGT6, the LCSC Liangshan development board is an open source development board. It has complete supporting video tutorials, document tutorials, and experimental cases. It provides an online compiler for a quick start in 10 minutes. Open source technology iteration and project-based learning make learning more in-depth and creativity sublimated.
LCSC Liangshan Development Board Background
Origin
The development board is a project with almost no pain points. Why does the JLC group want to enter this niche market? Since software development is more attractive than hardware development, the learning cost is low (one computer can dominate the world), and the market demand is also high. It has caused more and more people to turn to software development. Hardware is the carrier of software, and the entire ecosystem of JLC relies on the group of hardware engineers. We hope to do something for this potential family. Thus, this project was born.
Why Choose the High-end GD32 as the Main Controller?
We have tried many solutions. Eventually, we used the high-end GD32F470ZGT6 chip to prevent performance from limiting everyone’s imagination and innovation.
LCSC Liangshan development board has completed its development, and we are currently troubled with pricing and naming. At that time, global chip prices were on the rise, with many chips experiencing several price changes a day. The GD32 main controller we selected has also been fluctuating around 108 yuan. At this juncture, the founder of the EDA software suggested that we name it the Liangshan. Regardless of price increases or decreases, our development board will be sold for 108 yuan, not aiming to profit from selling boards, but focusing on cultivating engineers as our mission.
Liangshan comes from the novel “Outlaws of the Marsh,” also known as”Water Margin.” It is one of the four classic Chinese classics. The story revolves around 108 outlaws and rebels who gather at Mount Liang (Liangshan) to form a formidable army.
Problems that LCSC Liangshan Development Board Can Solve
- Humanized design with rich expansion interfaces, greatly expands playability and usability. It uses GD32 series chips with powerful performance.
- On the premise of ensuring practical functions, LCSC Liangshan development board is designed to be miniaturized, easy to carry, and suitable for project expansion. It can be used in electronic design competitions and similar events.
- It solves the problem of beginners who are getting started with development boards. There are not many development board tutorial cases used, and they cannot directly apply them to project development after learning.
- Highly cost-effective and high-quality, our LCSC Liangshan development board is priced at 108 yuan. It is worth buying, easy to use, and trustworthy.
- One-stop service. By purchasing the LCSC Liangshan development board, you can not only acquire embedded knowledge but also learn to design various embedded expansion projects. The JLC group provides a wealth of educational resources and leverages the complete industrial chain of JLC to assist students in completing the design of a comprehensive electronic product project. This includes PCB design, component procurement, PCB fabrication, and 3D printing. Through our open-source platform, you can connect with electronics enthusiasts worldwide, exchange ideas, learn embedded development and debugging techniques, enhance your practical skills, and uncover the mysteries and marvels of embedded systems.
