34-Pin Connector B
The A4SAP-H motherboard combines JCOM1 and J3 into a 34-pin, 2.0 mm pitch pin header, including two RS-232/422/485 connections and an audio (Mic-in/Headphone-out) connection. Refer to the table below for pin definitions and the female mating connector information. The distance between board-to-board stack is 11 mm in height while using male pin header (PINREX P/N:225-97-17GBEW) to stack onto female mating connector (PINREX P/N:620-92-17GB00).
For a detailed diagram of the A4SAP-H motherboard, see the layout under Motherboard Quick Reference.
