# The Pinout sign of WIZwiki-W7500P PCB Board

## Question

Asked by ezheng on 2016-02-22 in MCU & Boards.

Hi Everyone,

I found the pinout sign of WIZwiki-W7500P PCB board not match with the schematic of WIZwiki-W7500P. For example, at PCB board, D7 Pin is PC_06; but at schematic, D7 is PA_12.

Have any one tested the W7500P board, I want to know which pinout sign is correct.

Thanks very much!

Edward

Hi,

What I said is WIZwiki-W7500P PCB Board Pinout sign not match with the WIZwizi-W7500P schematic. Please note, all I mentioned is W7500P developing board, not W7500

For example:

PCB Pin sign Schematic Pin sign

D2 - PC_01 D2 - PC_03
D3 - PC_00 D3 - PC_02
D7 - PC_06 D7 - PA_12
D8 - PC_07 D8 - PA_11
D9 - PC_04 D9 - PC_01

Please check this issue, because it confused me for several days.

Hi.

It is correct schematic. And wrong PCB Silk.

We have plan to modify in PCB silk.

D2 - PC_03
D3 - PC_02
D7 - PA_12
D8 - PA_11
D9 - PC_01

Up list correct.

Thank you.
