Installation Steps

1>.Step 1: Install 1pcs SOP-16 RDA5807PF at U1.There is a dot on one corner of the IC and there is a rectangle pad on PCB where the Pin1 of IC can place on.These two marks are corresponding to each other and are used to specify the installation direction of the IC.
2>.Step 2: Install 1pcs 30K ohm Resistor at R1.
3>.Step 3: Install 1pcs 0.1uH Inductor at L1.
4>.Step 4: Install 2pcs 1uH Inductor at L2,L3.
5>.Step 5: Install 1pcs 32.768KHz Crystal Oscillator at Y1.
6>.Step 6: Install 1pcs 24pF Ceramic Capacitor at C1.
7>.Step 7: Install 1pcs 0.01pF(103) Ceramic Capacitor at C2.
8>.Step 8: Install 1pcs 0.022pF(223) Ceramic Capacitor at C3.
9>.Step 9: Install 5pcs 6*6*5mm Switch at S1-S5.
10>.Step 10: Install 1pcs 100uF 16V Electrolytic Capacitor at C4,C5. Please pay attention to the positive and negative poles. The shorter pin is the negative pole.
11>.Step 11: Install 1pcs 3.5mm Audio Jack at J1.
12>.Step 12: Connect battery box.Pay attention to positive and negative.
