DC Power Jack Input (J4)
- The inner pin is positive voltage becoming the +VDC_IN signal on the expansion board. The +VDC_IN signal passes through a discrete circuit that provides polarity protection and filtering before reaching the input power multiplexer, U18.
- Outer ring is ground; this is common with module ground and connector shields.
- The jack accepts a 5.5 mm plug to a depth of 8.9 mm.
