I2C RTC: Maxim-IC DS3231 "Very accurate real time clock" - low voltage RTC.

I2C RTC: Maxim-IC DS3231 "Very accurate real time clock" - low voltage RTC.
We designed a 0.1 space carrier board and below the 2 mm headers, on the top layer, installed this SOIC16 RTC.
This clock works extremely well +- 2 minutes per year. An alternative is Macetech's ChronoDot on an external
separate round PCB. <---- Seems too expensive ?

Project: Indoor environmental / security sensor mesh network.
All scripts are "beta" ... further testing on going.
Enjoy :cool:

Do you have this FILE in PDF.

HELP!


DO YOU HAVE A SCHEMATIC TO YOUR RTC PROJECT?

[RFAndy]

This file can be easily read with any text editor.
I rechecked this file and there are no problems. :confused:
Have you noticed 41 other users downloaded this file?

As for a schematic ... there is none ... it is very simple.
The SCL from the DS3231 goes to GP1O18 (SCL) on the proto board.
The SDA from the DS3231 goes to GPIO17 (SDA) on the proto board.
Also ditto the +3.2 VDC and ground. :cool:

BTW ... All wiring information is contained in the source file eg. "RTC_DS3231_R4.py"

Some users (with some web browsers) have to use right-click "Save file As" instead of left-click.

Thanks for posting your example script!
