i.MX 8QuadXPlus MEK Board Hardware User's
Guide

1. Introduction

This document is the Hardware User's Guide for the
i.MX 8QuadXPlus Multisensory Enablement Kit (MEK)
based on the NXP Semiconductor's i.MX 8QuadXPlus
Applications Processor. This board is fully supported by
NXP Semiconductor. The user guide includes system
setup and debugging, and provides detailed information
on the overall design and usage of the MEK board from a
hardware system perspective.

1.1. Board Overview

The MEK board is a platform designed to showcase the
most commonly used features of the i.MX 8QuadXPlus
Applications Processor in a small, low cost package. The
i.MX 8QuadXPlus MEK board is a development board,
which gives the user the option of becoming familiar
with the processor before starting development.
Table
1 lists the features of the i.MX 8QuadXPlus MEK
