# AVDD PINS DISCONNECTED W5500

## Question

Asked by germacovitch on 2023-03-05 in Ethernet Chips.

Hi

We had a problem during the manufacture of a new prototype: Just one AVDD (pin 4) pins is connected in our board.

It seems the AVDD pins are not connected together internally . I am wondering if could use our prototy by connnecting just a few more AVDD pins. THe is no way to wire up all of them.

Any advise is welcome

You answered your question yourself. Find someone with skills and tools to wire all the AVDD pins for you.
