Moxa W315A-LX [5/24] Overview

W321/341 Hardware Introduction

1-2

Overview

W321/341 Series wireless embedded computers are 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 802.11 b/g/n 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 W321/341 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.
