Help with setting up v4.5 pcb for a beginner

I’m very much a beginner when it comes to all of this, discourse included so I apologize if this lands in the wrong spot. I’m struggling to get my first setup up and going. I have a v4.5 pcb have flashed teensy and f9p, soldered everything. I have tested f9p plugging directly to tablet and I can get a correction from it. This evening I was attempting my first test on the bench, I have power and ground ran through the 23 pin, and Ethernet connected to my pc. Nothing will show up in ag i/o, if I connect usb to teensy it immediately shows up as correctly configured and I get lights at Ethernet port and on imu. When connected this way the f9p doesn’t show up on my pc. What am I doing wrong? Thanks for the understanding.

Hsve you been the the ethernet configuration for your tablet?
Do you have the 6 little pins soldierd in the board and also the teensy?
Have you tried a different ethernet cable
Maybe put a picture up of your board

I’m using my pc on the bench currently, I have the Ethernet setup as the instructions say. 6 pins are soldered, have tried a different Ethernet. I have no power to anything without the usb cable attached it appears, although I’ve checked my 12v circuit on the board and it is functional.

As I’m looking the board over trying to understand, I see there is leds for the teensy/imu and another for the gnss that aren’t lit up and isn’t 5v at the test location either.
Imu lights up when usb is connected and the 5v was led is lit up as normal when board connected to power(without usb or Ethernet connected)

well, just realized that my boards are missing two transistors which explains all my problems, guess i missed that when i ordered PCB

Those are voltage regulators, yes thats the problem.

Your also missing the 3 led lights at the front aswell, weather this matters im not sure

If you’re using the “Lock” Pin, you should add the missing heat sink on the mosfet
