PoE hat needs stackable headers

Sat Dec 08, 2018 4:07 am

The PoE hat really needs to come with stackable headers for the 40 pins. Clearly this hat is just a power substation for the micro USB and so stackable headers would preserve the functionality of the Raspberry Pi 3 B+. I can't think of any good reason why this wasn't included as part of the hat from the start.

Does anyone know why this has was designed without stackable headers?

Presumably it was to keep down the price and keep the overall height down so that it would fit in cases more easily.
However, they did promote 3rd-party push through pins on launch day - see the blog

This tutorial explains what is needed to extend the GPIO Pins:

Thank you for the link, I was aware of this kludge however it adds height, 6mm, and will make the fan less effective. It would be better to have the hat without any header and have the ability to install a stackable header. Better would be to have the stackable header installed at the factory.

The problem then comes form the people not wanting to stack anything on the header, I would guess their target market asking for PoE in a HAT over to bother adding the pins and capable Ethernet just don't need them.

They can't please everyone.


Just skimmed that second MakerSpace link, (*) but on the topside if you take the black covers off the passthrough connector you should should be able to gain a little bit.



(*)get out clause, I don't have a PoE HAT, I do have a sensehat that uses the same passthrough connector
