What is a public pcb?

Hardware) is based on the principle of open sharing, publishing shared circuit board design files in some electronic design platforms or open source communities. These public PCBs are usually free, open source and open hardware, which can be used, modified, copied and shared freely.

Public PCB not only helps to quickly complete the circuit design and PCB layout design, but also helps to accelerate the design study, design communication and design exploration of engineers. In addition, the use of public PCB can also avoid the tedious process of designing, testing and manufacturing circuit boards from scratch, so as to better buy good quality and effectively save design time and cost.

Some public PCB design platforms, such as easyEDA and OSH Park, provide a large number of public PCB design documents, including Arduino and Raspberry.

Pi, ESP32 and other microcontroller circuit boards, analog circuit boards, sensor circuit boards and other circuit boards. At the same time, these platforms also provide online PCB drawing tools, users can quickly draw and upload their own circuit boards, and get reference and suggestions from other designers and engineers.
