This 3d printed case houses the already small [TP-Link TL-WR703N] but also makes room for a custom-made expansion board. The expansion board is created to make the device a lot more hacker friendly, and who doesn’t need a great case to hold it?
Since the router board already has a USB port (intended for use with USB 3G modems) the add-on acts as a USB hub. The stock USB connector is replaced by a pin header which mates with a DIL socket on the underside of the expansion board. through the use of an FTDI chip the expander uses three USB ports and a 2×10 pin header to break out the GPIO pins from the router’s processor. only two USB ports are visible in the image above. That’s because the third is recessed, and an opening has not been added to the enclosure. This struck us as odd until we read that the port is indicated to be used with a low-profile thumb drive, essentially adding internal storage for the device.
