Board Component

Description

24-pin header connector

This is the top side of the 24 pin connector used to make power and

input/output pin signal connections to the EVK board. This is a 2x12,

2mm pitch connector (see EVK component list for part number). The

connector can be used to connect to individual pin headers, ribbon cable

connectors, or can be used as a module and plug into a female connector

on the host target system.

Super Capacitor

Can be used as the VBAT (backup) supply power source of the AB18X5.

VCC current

measurement pins

These pins are in series with the VCC supply pin of the AB18X5 and are

used to connect to an external pico-ammeter for measuring the VCC

current into the AB18X5 device. The connection polarity is shown in the

diagram.
