Som-4470 - Advantech SOM-ETX Series Design Manual

2.2.5 SOM-4470

With a fanless low power Intel Pentium III processor, a rock solid 440BX system
chipset and Intel 82559ER Ethernet chipset, the SOM-4470 can support the most
demanding embedded applications. Used in conjunction with an easily designed
customer solution board, the SOM-4470 can be quickly utilized for video and data
intensive applications that need power and speed. One of the smallest Pentium III
fanless solutions on the market today, this module gives developers a platform that
accelerates their development time, while maintaining the capability, performance
and durability of the application.
