I use W5500 stm32 board module, the use of dupont lines to connect, but found that when dupont line length is slightly longer, my W5500 module cannot connect to the server, what reason is this? How to solve?

CodePudding user response:

When the signal frequency is higher, longer lead will have influence, want to learn more or to do circuit board is more appropriate,

CodePudding user response:

So high data rate, so the anti-interference requirements is very high, easily disturbed, you can put the root 2 make it twisted pair of dupont line 2 (same twisted-pair cable), the anti-interference ability will be greatly improved
