@Vilmalith I'm certainly not in a position to know.  But all of the recent TP-Link business class hardware (e.g. EAP225 V3, EAP245 V3) are all PoE.  They come with a midspan Ethernet power injector in the box.  I forget whether the OC200 supports PoE, I think mine is powered by micro-USB.

I would assume the EAP660 and 620 will be the same (e.g. PoE) -- unless for some reason the chipsets/radios will require more power than the PoE spec allows.  Most business class AP's from other vendors are all PoE these days.

@Vilmalith There is hardly any information about the new Omada line-up. There is the press-release, the CES2020 page, a YouTube video and some dead links to the English /omada-sdn/ page. None of these answer your question. The line-up was supposed to be released in Q1 but they silently missed that deadline yesterday.

@JSchnee21 The OC200 controller definitely supports PoE in. I'm hoping the 2.5Gb Omada switches included in the new lineup have a built-in controller so I can ditch the dedicated box.
