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).
