Description

Note: More pictures will follow shortly.

Easy assembling of all parts by following the provided pictures and the documentation included with the kit (basically matching parts to the positions on the PCB).

The finished clock will show the time and room temperature. It comes with an alarm function and an automated dimming function to lower the brightness at night.

We believe it shows time in 24H mode only and temperature in Celsius.

A CR1220 backup battery keeps the time also if there is no main power supply is available.
