The only RS3231 available in store (without ordering on line) that I could find is a "mini" version, which has a different pin layout than the normal larger modules typically used in tutorials. I went ahead and purchased it as it was quite inexpensive. However I can't find documentation on how to use it, and now I am worried it might not work as per the normal module. The website suggests its compatible with Arduino and Pi devices.
The pin labels are partly obscured, they appear to be labeled:
+, D, C, NC, -
I wonder if anyone knows about this module or has seen documentation on it. (I've already spent 30 minutes googling for info and have not been able to stumble across search keywords that give me the correct information)
