The following blog post mentioned a new BitScpoe product that was described as likely to be available at about the same time as the Raspberry Pi PoE Hat (now available...):
There was very little detail in the post apart from one CAD diagram with Bi3B+ in situ.
Is there any more detail? I was hoping that it could accept a PoE directly without an external splitter and utilise Bitscope board's more robust power management and breakout several more 5V feeds in addition to the Pi3B+'s USB ports which the new Raspi Foundation new PoE board wont do as far as I can see.
