# WizFi 250

## Question

Asked by Andrey on 2014-04-28 in Wireless.

Hi.
I have several technical questions about WizFi250.

1. Is WizFi250 have unique MAC address?

2. I don’t understand about 60 I/O pin. Is it SLEEP_CLK or NC ? Is it need for sleep mode?

Thank you.

Hello Andrey

If you have a document described as <pin 60> connected <SLEEP_CLK>, please ignore it.
It’s a kind of misprint.
As Kaizen said, <pin 60> is N/C.

The latest documents are below.
Please refer to them.
