| | The peculiar thing about the internal USB socket is that I can plug in any host-powered wireless module that I want. It certainly is cheaper than trying to fit a wireless module onto the custom board. At least in the low volumes that I'm thinking of. You could also fit it with different types of modules based on the requirements, for example a USB to Wireless chip for wireless applications, or a Bluetooth dongle for a link with a handset. Why spend more money if you can just take a DLink module, strip its shell and place it in this device for $20? | | The peculiar thing about the internal USB socket is that I can plug in any host-powered wireless module that I want.
