Thank you for the information. I'm new to all of this and had got some mismatched info from someone local here that has never used them in a real pinball. Turns out they were using an old shield with components that were missing to run in a real pin.
I've got the harness/wiring ready to connect to the header of my power driver board as specified.
The soldering part for the red/black wires with the white connector that go to the LED panels, I see they plug into the panels in your picture above (one on each side) but the other end of that cable I can't see in your picture. I assume it connects to the blue connector that is to the left of the 12V DC power input connector?
Finally, I have been looking for the panels to buy on Ali express and there are so many different options. Lucky1 referred me to a certain place but they have many different options such as brightness levels etc. I see a lot of people say that they never go to the full brightness that the panel is capable of so I was thinking of just getting the lower end ones as long as all the rest of the parts are the same in terms of quality. The one I am looking at is a P2.5 64x32 with 1600 brightness. The higher ones are 2000 and 2400 but I am not sure I need those.
Do they all ship with the power and signal cables or is that extra as well?
Thanks again for your time, I really appreciate it.
