The RFX Gateway is now offered in fully pre-assembled form, complete with the Raspberry Pi motherboard and RFX perspex case.
The other option is the RFX Gateway in “BYO” kit form, which does not include the Raspberry Pi. The RFX Perspex case is an optional addition in the “BYO” kit form.
The fully assembled Gateway option is designed to appeal to those who would prefer to have everything assembled and ready to go out of the box (Note: You will still needs to provide an appropriate 5V power supply for the Raspberry Pi, and an Ethernet cable to connect to your LAN).
The “BYO” kit is designed to appeal to those who may already have a Raspberry Pi they wish to use, or otherwise prefer to source their own.
