+### Design Notes PAM8403
5
+* Two ends of C32 and C34 must connect over PVDD and PGND.
6
+* To prevent to noises to speaker:<br />
7
+ * Pin 3 and Pin 14 should go under the IC to the speaker
8
+ * Pin 4 and Pin 13 should NOT go under the IC to the speaker
9
+ * Pin 2 and Pin 15 should NOT go under the IC to the speaker
10
+* Pin 6 VDD should separated with PVDD, pass C36 cap and after relatively long distance, and finally connect to VCC pin from two trace lines (to make this distance).
11
+* Not recommended to use single layer board.
12
+* circuits in the dot line box is optional.
