WiFiG25 is a cost-effective System-on-Module (SoM) thought of to drastically reduce the development time needed to design a low-power and low-EMI Linux Embedded device.

The more complex hardware like CPU, RAM, Flash, WiFi, power and EMI components are integrated on a single SMD component in just 50x30 mm using an complex six layers PCB permitting hardware designers to create their simple and cheap carrier boards.
