Involvement:General (knows how to use it) - Ownership:more than 1 month
Neat little package. the battery is included. Plenty of information on the internet about the DS1307. Cheap enough too.
As usual no connection information. however there is plenty of information on the internet about the chip, its application and example code. I found that the pin markings on this module were different from the tutorial I was following but there is enough information out there to figure it out.
I had a bit of trouble getting the initial time set, but that's due to my understanding (or lack thereof), of the code I was using. Once it was set the unit is fire and forget: I power my project on, the time is displayed.
Saves you from resetting the time on your project every time you disconnect the power. For the price, why wouldn't you use it?!
