Chapter 1 Introduction

The ThinkCore W300 Series is a line of wireless RISC-based embedded computers that feature

802.11a/b/g WLAN, RS-232/422/485 serial ports, and an Ethernet port in a small, rugged chassis.
In addition, the W321 and W341 models feature an SD slot, and the W341 features two USB 2.0
hosts and one relay output channel.

As part of the W300 Series, your embedded computer is ideal for diverse, machine-to-machine
embedded applications. It enables wireless operation of traditionally wired network and serial
devices and not only provides transparent data transfer, but also numeric computing, protocol
conversion, data processing and even data encryption. You will find it easier to build embedded
systems for distributed peer-to-peer communication, turn wired devices into wireless devices, and
introduce higher mobility and more intelligence to your system. In this chapter, learn about the
capabilities of the embedded computer.

This chapter covers the following topics:

ThinkCore W311/321/341 Hardware User’s Manual Introduction

Overview

The ThinkCore W300 Series wireless embedded computer is designed around the MOXA ART
ARM9 32-bit RISC processor. Unlike the X86 CPU, which uses a CISC design, the MOXA ART
ARM9 uses RISC architecture and modern semiconductor technology to provide a powerful
computing engine without generating significant heat. The processor also integrates UART and
LAN functions to provide exceptional communication performance, but without the bus bandwidth
limitations associated with general ARM-based communication products.

On-board NOR Flash ROM and SDRAM provides ample storage capacity, and for select models,
the SD slot gives applications extra room to expand. The built-in WLAN function supports the

802.11a/b/g standard, providing transmission security with WEP, WPA and WPA2. The backup
LAN port not only provides an alternative solution for networking but also supports Ethernet
clients, allowing any network device to plug in and connect to the WLAN. The built-in
RS-232/422/485 serial ports support a wide range of serial devices, making this platform suitable
for data acquisition and protocol conversion applications.

The Linux-based operating system comes pre-installed and ready to run, providing an open
platform for software development. Software written for desktop PCs can easily be ported to
W300 Series embedded computers by using a common complier, so little time is spent modifying
existing software code. In addition, the operating system, device drivers, and user-developed
software can all be stored in the built-in flash memory.
