The J4 power jack on the expansion board is a surface mounted, RoHS compliant device. The connector is manufactured by CUI INC* as model number: PJ-002AH-SMT-TR.

  • 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.

Refer to the manufacturer’s datasheet for additional details and the latest information.
