All,

Do you know if M3 have build in RTC ? if yes, is that mean I can easily plug the battery into the RTC Battery header will do? any program I need to run / setup prior RTC working?

I am developing an mobile solution and require the time but I won't want to add in extra module if it was built in.

Thanks,
Kent

There is a place to solder a 2 pin header to the board and then you can plug in a battery. The pitch is 2.54mm and it's behind the USB and Ethernet ports next the I2S header. On my boards it's unsoldered.

Dave,
thank you and I found it on my board too! so after I setup the battery there, it will remember the date/time even I power off ?
Sorry I am still learning that !!

thanks alot!

Yes, that is the idea behind having a battery for this purpose.
