Chapter 1 Introduction

The RISC-based wireless embedded computer, ThinkCore W300 Series, including W311, W321
and W341, features 802.11a/b/g WLAN, 1/2/4 RS-232/422/485 serial ports, Ethernet, and SD
socket as well as the two USB 2.0 hosts and one relay output channel for W341 into a mini size,
rugged chassis, to provide users the experience with a small package, versatile communication and
strong computing platform. To use ThinkCore W341/321/311 Series Embedded Computer, the
network device or serial device will become the wireless device and fulfill the demand to do the
numeric computing, protocol conversion, data processing and even data encryption, not only the
simply data transparent transferring. This will help user to build peer-to-peer, distributed wireless
communication embedded system, make traditional wired devices wireless, provide higher
mobility and more intelligence. It is really ideal for the diverse M2M embedded applications.

ThinkCore W341/321/311 Hardware User’s Manual Hardware Introduction

Overview

ThinkCore W300 Series use the MOXA ART ARM9 32-bit RISC processor. Unlike the X86 CPU,
which uses a CISC design, the ARM9’s RISC design architecture and modern semiconductor
technology provide ThinkCore W341/321/311 with a powerful computing engine, but without
generating too much heat. In addition to the ARM9 core, the MOXA ART ARM9 processor
integrates UART and LAN functions, provide the extreme communication performance without
the bus bandwidth limitation as general ARM-based communication products.

Moreover, the on-board NOR Flash ROM and SDRAM give you enough storage capacity and the
additional SD socket provide the flexible storage expansion to run applications. The built-in
WLAN function supports the popular 802.11a/b/g standard, provide the transmission security
including WEP, WPA and WPA2. The backup LAN port not only provides the alternative solution
on networking but also supports the Ethernet Client capability, to make the network device to be
hooked on WLAN by easily plug-in step. Besides, the RS-232/422/485 serial ports allow you to
connect a variety of different types of serial device, make this communication platform suitable for
some of the more simple data acquisition and protocol conversion applications.

The pre-installed ready-to-run Linux-based operating system provides an open software operating
system for software program development. This means that software written for desktop PCs is
easily ported to ThinkCore W341/321/311 by using a common complier, so that you will not need
to spend time modifying existing software code. The Operating System, device drivers, and your
own software can all be stored in ThinkCore W300’s Flash memory.
