MB-COME-1 for COM Express: COM Express Mainboard (carrier board)


The COM Express mainboard (carrier board) MB-COME-1 in combination with a standard COM Express module forms a very compact hardware kit that can be used for a freely scalable embedded PC platform thanks to its modular design. Because of this – with uniform interfaces and mechanical dimensions – the PC system can be easily adjusted to suit the requirements of the application. The many extension options and storage media that can be added offer a high level of flexibility and allow functionalities and performance to be extended easily, quickly and inexpensively. Typical uses are found in embedded server applications, PC systems for automation, visualisation and monitoring and all applications that place high demands on quality, durability and long-term availability.
