T-Relay 8 channel doesn't work with W5500 Shield attached

[bartoszkaminski]

Hello!

I purchased LilyGo T-Relay 8ch and I wanted to use it with T-Relay W5500 shield to have Ethernet. I soldered all pins of the shield but now my relay board doesn’t start at all. When I supply 12V to the relay board there’s no reaction, it doesn’t go online. Ethernet port doesn’t blink when cable is attached.

Can you help me figure out what is wrong? Before soldering the shield I had ESPHome installed on the relay board and it worked perfectly.

Hello, thank you for your report. I noticed that you seem to have soldered the W5500 module to the bottom of the board. Doing so will cause both boards to short circuit. The correct approach is to solder the W5500 to the top of the main board, as shown in the following image.

I was assuming that two square pins must be connected together.

Can you confirm that my understanding of pins orientation is correct now?

BTW, do you think I fried the board? If it works after correctly connecting the shield then I'm good or will its lifespan be limited due to the fact that I shorted it?

Yes, the connection method you are demonstrating now is correct. Could you try this method to see if the device can function properly? Previously, reversing the power supply might have caused a short circuit on the board.
