Short Description 

The SBC-LS1028A is a small computer system consisting of  

■ 

the MPX-LS1028A 

module, based on NXP’s LS1028A Industrial Applications 

Processor 

■ 

and the CRX07 carrier board.  

 

It targets both 

■ 

evaluation of the respective MPX-LS1028A SOM 

■ 

direct usage as an industrial computing solution 

 

This document gives you an overview on the board's hardware features and capa-
bilities and how to take the first steps on the initial setup.
