The LP-8441 is a compact size PAC (Programmable Automation Controller
It equips a PXA270 CPU (520MHz) running a Linux 2.6.19 operating system and has 1 slot for I/O Expansion Modules.

User programs can be saved in external storage device, such as microSD Card, USB device or RAM via Ethernet.
The LinPAC SDK is provided for users to develop LinPAC I/O applications rapidly and easily when I-7000/8000/87k series I/O modules are used in the LP-8441. Users can develop LinPAC applications by using GNU C or Java Language.
In the meanwhile, all kinds of servers and functions built-in make the LP8441 more powerful and users will be able to operate LinPAC to achieve their own project smoothly. With LP-8000 series, users can achieve the redundancy function and it will make the whole control system safer.

The main purpose of LP-8441 is to allow the numerous enthusiastic Linux users to control their own embedded system easily within the Linux Environment.
