Actually, I was able to find that IC but in chinese version.. https://datasheet4u.com/datasheets/I-CORE/AiP1628/1571692 Looks like its some kind of low level chip that probably transforms low voltage signals into higher voltage, like the ones used on ethernet ports. Probably to power up the LCD leds.

I see now. Mine does not have those: I suspect those are some extra functionality that the chip marked as AIP16R (on the top) has but was not implemented. The OP's board maker tought it would be nice to make them into pins in the board at the very least, while my board maker simply left them unconnected. I was not able to find the specs for that AIP16R chip.

Mine does not have any pinholes near the lcd display. Send a pic, or/and trace their paths into some chip and see what that chip does by its id

@fedes_gl To list USB speeds, do You will get an output like: 480M is the important part, this is is usb2.0. for USB3.0 you will see 5G or 10G for 3.1 Also check your ethernet port speed with: (replace end0 with your ethernet device) And if im not mistaken, those are my 2 issues with this image: only usb2.0 and network speed of 100mbps. Making it similar to a 5 years old device.. Let me know if you found the same speeds.
