ZS-042 DS3231 RTC module

Charging the LIR2032 at 5V is not such a good idea, it will shorten the life of the battery. Charging a CR2032 is a BAD idea. Just cut the PCB trace between the diode and the 201 resistor and use a CR2032. Check the attached image "trace_cut.png" A CR2032 will last more than 10 years [trace_cut.png] [DS3231.jpg]
