RTC on FEZ Siper

Hello to all,

I need to add RTC fonction to a FEZ spyder to log events on an SD Card.

What kind of hardware to persist time when the board is not powered? And how to connect it to the board?

Thanks in advance for your aswers,

Yann.

You need to add a battery to socket Z

Hi EriSan,

Thanks for your quick answer.

Battery would be connected between ground and Pin 5 on socket Z right?

And what kind of battery should i use to preserve time for say 1 month?

Yes

A regular CR2032 will do the job (and much longer then 1 month)

Cool, thanks for your help.

you’re welcome

This would be a very useful module… But I guess it would be Z-port and model specific (but I’m pretty sure that’s what Z is for according to Gadgeteer) Too bad I already soldered all my extenders. I guess I’ll need to buy some more.
