No, this is not a kit, but I've published all the information, including a parts list, on orvio.github.io/LNGateway/ I've used aisler.net to manufacture the PCB, because they are able to work directly with KiCad files. The project files, including the kicad_pcb file are available here: github.com/orvio/LNGateway/releases/tag/V2.1 There might be other similar services available for this in your area.
Unfortunately I use NCE DCC system, LocoNet not compatible BUT... interesting and well presented video, thank you.
Is this a kit you can get?
