Embedded CPU Wireless Module
Eddy-CPU/WiFi v2.1

Eddy CPU Wireless Modules enable reliable serial to wireless network connectivity  to your devices with robust security. It is equipped with powerful ARM926EJ-S(210MHz) processor and sufficient memory capacity of 8MB Flash, 32MB SDRAM which is operated by stable real-time Linux 2.6.x based OS, Lemonix 56 programmable GPIO pins and convenient Windows/Linux operable IDE, LemonIDE allows developers with an easy and simple means of programming their customized applications. Eddy-CPU Wireless modules provide developers and OEMs a flexible yet simple way to integrate wireless network connectivity to their products.  

Lemonix is a Real Time Linux built on Linux kernel 2.6.x. Standard Linux kernel 2.6.x has been revised to support Real Time capability while retaining the stable traits and merits of Linux kernel 2.6.x. Real time scheduler, preemptive kernel and lock-break methods have been implemented on Lemonix to guarantee a maximum response latency of under 37 us enabling a stable and reliable means of real time communication.

SDK, API & Source Codes Support

Eddy is distinguished with other embedded device servers in that it can upload and execute customized user applications. To enable developers to program their own socket/serial communication applications with least amount of time and effort, SystemBase provides arrays of development support including, SDK (Software Development Kit), API (Application Programming Interface) and Source Codes to assist developments.

Development Kit

Eddy Development Kit provides an easy testing and evaluation environment for Eddy applications. Before integrating Eddy to user hardware, applications are first programmed and tested on the development board. Power, Ready, Communication Interface, and GPIO Serial Signal Status LEDs on the development board provides a visual guide in understanding Eddy operating status.

Windows Utility Support

High featured and easy-to-use utilities to monitor and test your finalized products over network and serial interface are provided at no cost. SystemBase management utilities, COM port redirector, PortView and TestView enables an accurate monitor and full administration of your inventions.
