eSOM270, a PXA270 Module with XScale processor can be used by customers who have the need for small changes in their design to suit the requirements of multiple customers. Another important factor for going in favor of the system on module approach is the volume. When the volume is low, going in for a module based solution is cost effective and faster. The time to market has become an important criterion and customers would not want to invest heavily on their development activities and would want a faster product development cycle.

Most of the time the Carrier boards designed around the eSOM270 is just 2 layered and hence faster design and manufacturing time. All the pins of PXA270 Microprocessor are brought to the SODIMM connector of eSOM270 and hence all the interfaces supported by PXA270 can be put in to use.
