1 Introduction

1.1 Overview

This document is a user guide for the RD-88MW322-QFN-1B-2A-v1.0 evaluation

kit. This evaluation kit is based on the NXP 88MW322, an IEEE 802.11b/g/n Wi-Fi

microcontroller.
The RD-88MW320-QFN-1B-2A-v1.0 evaluation kit, which is based on the NXP

88MW320, is similar.

Table 1

 summarizes the key differences between 88MW322 and 88MW320 (hereafter

referred to as “Wireless SoC”).
