Features:

1. Multi functional Electric clock, which can set date/week/time/alarm clock/temperature;

2. A digital clock controlled by a microcontroller with a supply voltage of 5V DC;

3. Using a dedicated timing chip DS1302, it can display hours, minutes, seconds, months, days, and weeks. With temperature measurement, music alarm clock, hour reminder, and brightness control;

4. Four digit Nixie tube, control adjustment button, memory battery, all functions are realized by two user keys;

5. Paired with a USB to DC power cord, it is easy to use and installation instructions. There are four melodies to choose from for alarm music.

Note: This is an unassembled kit, you need to assemble and solder.
