Hardware Introduction 

The UC-7122/7124 embedded computers are compact, well-designed, and built rugged enough for industrial 
applications. The small pocket size of the computers makes them suitable for a variety of operating 
environments. LED indicators help you monitor the performance and identify trouble spots, and the reliable 
hardware platform allows you to devote your attention to developing your application. In this chapter, learn the 
basics about the embedded computer hardware and its different parts. 

The following topics are covered in this chapter:
