WeTek Air support plans?

Did I get it right that on the pics here the board is turned upside down?..I mean if you say the top is where the soc is.

So gpio pins are upside down. That’s how the second tuner board is connected.
But what about the 5V Output pogo pins?.. I don’t get why they are needed anyways. It’s not for power supply right? what are they needed for?

Does it get hot? Do you use heatsink+fan?
or @anon88919003 … idk whose setup it is.
