Miniature built-in clock/voltmeter/thermometer module with red indicator. A popular application is in-car dashboard integration.
There are two buttons on the module. The left one is to switch to the setting mode, the right one is to change the display mode (time, date, temperature, voltage or alternate) or to change the settings. Contact pads for soldering remote buttons are located on the module board.
The module contains a DS1302 real-time clock microcircuit complete with a CR1220 3V battery, which ensures that the clock runs even in the absence of power (the display does not light up).

Displaying the value of the supply voltage:
The temperature measurement error is corrected using the Ac parameter. Correction range from -5 to +5 degrees:
Correction of the clock rate accuracy for a day is performed using the Ad parameter. Correction range from -9 to +9 seconds per day:
The alternate display option can be set using the dd parameter:
0 - time/temperature/voltage;
1 - time/voltage; only time; only tension; date only; temperature only;
2 - time/temperature; only time; only tension; date only; temperature only;
