A universal connector J3 combines all audio, power and control connection points. J3 is arranged as a
16-pin dual row 0.100"x0.100" PCB pattern that can accept a standard straight or right angle header.
With a header installed, the connector J3 may be used as a mechanical mounting feature for the VCM
board. The J3 connector pin assignment is summarized in a Table 1.
