Khadas VIM4 PoE with M2X shield

Hello.
I’ve got a Vim4 board and PoE shield for it. When I plug in power adapter without PoE shield, board starts and works perfectly, but with shield connected it starts once per 10 times. Could the problem originate from a small interconnection black/red cord? Or, maybe, in connectors? Or my PoE shield is broken?

Hi @Vsaritos
Are you able to provide further details of the PoE router to us?

Basically, you will need to ensure the PoE module able to provide up to 24W powers.

Good day!

I’ve left comment to my order on AliExpress.
I’ve ordered a separate 12V 2A (as I saw it in your shop on AliExpress) PoE injector adapter. The problem is - board does not start with connected shield and type-c adapter (diode flashes or lites in half-voltage) and diode does not lite on at all with PoE adapter connected.
With m2x disconnected sbc works like a charm.
12V 2A are from the m2x spec. This gives 24W power supply. :grin:

Hi, @Gouwa.
Here are some videos of the problem.

Hello @Vsaritos

Does Type-C adaptor power on well if you just connect M2X board to M.2 connect and not connect the VIN cable ?

Hello, @numbqq. No, the board does not start with m2x connected to m2 and VIN cable not connected. See video below.

I’ve checked m2 connector on vim4 with m2 nvme disk and it works perfectly, so the problem is :100: with m2x shield…
