This video introduces to you how to choose the fan hole type when designing fan holes in PCB, how to choose the size of via holes and via pad size when fan holes are designed, and how to target different centers after the fan holes are completed before PCB wiring. How to calculate the size selection of each value when setting the rules. It also gives the considerations when sharing vias on the same network. It also introduces how the designer can pass the wiring after the fan holes are completed. Adjust the position of the vias to achieve optimal routing channel conditions. By studying this video, everyone will have a comprehensive understanding of PCB fan holes.

- CC1101 can only send data once
- I use CC1101+STM8. The two modules can communicate, but they can only send and receive once. The receiving end must be reset before it can receive again. It is impossible to receive data continuously.
