Hi everybody I am interested if there is an Arduino or an Arduino compatible bored that actually have on it a RTC.

Because I am in the middle of making a project that needs very importantly a RTC but I am very bad in soldering and the RTC witch I am using (DS1307) haves very little holes, and the soldering just does not work for me.

If anyone can help I am going to be very happy!!!

Thanks everybody.

 

None that I know of, but there is an RTC breakout board kit that attaches to an Arduino. I know because I am using one.
It's sold by Adafruit and is likely not the only solution. Click here.

 

I've seen one with RTC on it (justcan't find it now)..
But as dj said just buy an RTC module..

 

The samd21 has one, so that would be the zero?
The ds1307 doesn't have alarm outputs for sleep mode interrupts. Just saying.

 

Does it mean that when we use the time library it works as accrete as a RTC?

And how do we connect a bake up battery to it.

 

hi EM,
Have a look at this link, its a VERY accurate RTC with built in battery.
I use them, they work OK.

The DS1307 module I linked to also has a built-in battery.

Instead Orin addition to the Time library, there is an RTCLIB library. I think there's a link to it from the link I shared.

Aha, I thought so. Click here.
