PiOLED + Waveshare POE hat?

Support Product Questions
1

Hi,

Does anyone know if these holes on the Waveshare Power over Ethernet HAT (D) (Pi 3B+/4B) can be used to solder pin headers in order to access most of the pins the hat covers? I want to use a PiOled with the hat attached via jumper cables, So I was thinking:

  1. 2x 5v from hat holes
  2. SDA from hat hole
  3. 3.3v from pin 17
  4. Pin 5, Pin 6 - direct connection to Pi GPIO

Circled the holes above, I couldn’t find any info about them on waveshare wiki. I feel like this should work, does anyone know?
