1. Function.

1>. It is DIY kit. User need to weld it.

2>. Clock display. Display hour and minutes minute under normal circumstances on 4-Bit digital tube.

3>. Display seconds on LEDs.

4>. Hour,minute and second can be adjusted independently.

5>. Timekeeping function.

6>. 2-Channel independent alarm.

7 > . seconds composed of 60 LED , the number of liters can be accurately synchronized with the number of seconds (this is the circuit is different from other rotating electronic clock\'s biggest feature), of which 48 white LED at the local White warm white bright light tube, sweet is the colorful night light. Each light-emitting diode is independent of the current limiting resistor to ensure long-term stable operation.

2. NOTE.

1>. There are 13 short circuit pad marked J1 to J13. User can weld it by pin from other components such as metal film resistors or LEDs.

2>. DC2 on PCB is standby power.

3>. Input power is 4.5V-5.5V. If users don’t use standby power ,you don’t need weld VD1-2(1N5819) on PCB but need to weld pad which has marked “A”.
