Computer-on-Modules(CoM) are available in a wide range of variants and sizes. Some COM modules are carrier boards for industrial computers onto which small boards can be plugged.
The CoM technology is suitable when the carrier board is developed in-house and the CPU alone or in combination with the chipset and the main memory is purchased as a standard product. The DIMM PC module is such a technology. It is a plug-in computer module that uses the plug-in technology of DIMM modules. The DIMM PC module contains an 80386 or 80486processor and its main memory. Due to the small size of the board, it cannot accommodate Pentium CPUs.
