== Feature ==
* PCB parameter: 110.4 x 34 x 1.6mm (Blue)
* Parameter with case: 122.8 x 51.4 x 29mm
* Digital Tube working voltage: DC 5V
* Operating Current: around 50MA
== Function ==
* Exact timing: Adopts DS3231 chips, official said the accuracy comes to 2PPM.
* Chime on every hour: User can set the hour time randomly and choose the ring you like.
* Dual Alarm clock: Dual independent alarm clock, user can set the duration and ring.
* Temperature: It has the Centigrade and the Fahrenheit, which can be calibrated.
* Intelligent light control: It can lower the brightness when gets dark, user can set the light control level (total 5 level) according to preferences.
* 12-hour/ 24-hour display
* Display by circle: The Time, Tempreture, Date and Week display in circle. It only shows time when you close the circle display.
