( C4 , C5 ), Monolithic (C2 , C3 ), Crystal oscillator (Y1) , Keys (S1, S2).
Distinguishing positive and negative elements:LED(D1~D60),Battery seat(BT1),Electrolytic capacitor(C1),
Buzzer(LS1),These elements should be noted that the positive and negative poles of the circuit board are to be noted.
Other multi pin element:IAP15W413AS ( U1), DS1302( U2), S8550( Q1 ), Block USB (USB1), These
elements should be notedsame direction as the circuit board.
3,Positive welding LED, digital tube, Thermistor, and components of the weldingback.
4,LED has two colors, the less number of color welding in a large number of corresponding position, and the rest of the
location of a number of more than one color.
5,U2, C4, C5, Y1, BT1 must be welded before the digital tube, pay attention to the points on the digital tube.
6,The working voltage of the kit is 5V, the on back is only for the power down save time.
