Do I have the latest revision official POE hat? (re: L-C filter and no mezzanine)

Mon Dec 23, 2019 2:56 pm

I've just purchased the official Raspberry Pi POE Hat (from Adafruit) but I'm not sure if this is the latest revision.

I know the initial release of the POE hat had a problem and they were recalled and had a 'mezzanine with L-C filter' installed. I've purchased POE hats before and they all had the mezzanine.

However, my latest purchase doesn't have it but appears to have the L-C filter directly on-board:

Is this version a later revision (i.e. safe to use)?

Thanks very much for the reply. I saw that page The Pi Hut but it doesn't show both sides of the POE hat.

I've also searched for "PI POE 2.0" and can't find any official articles about it.

That is the revised board with the filter integrated. The original board doesn't have the components to the right of the fan.

Look at the "Notices" section towards the bottom of this page...
