Real Time Clock 1805 (QWIIC)

Qwiic System

Specifications of the 1805 RTC claim accuracy of a couple of minutes per year. The board I am using loses half a minute per 24 hrs, about 2 orders of magnitude worse than specs. Even worse than my $20 coffee maker.

Is this a fluke? What am I doing wrong? Special setting? Please advice.

Hello Hans.

When did you purchase your SparkFun Real Time Clock Module - RV-1805 and was it directly from SparkFun or a distributor?
