[HELP] Raspberry Pi Zero W V1.1 - Test Pads problem
Hello Community,
I'm facing a problem and I can't find a specification document on the internet about the new RPi Zero W, the one with the built in wifi.
My problem is the back of the RPi where the Test Pads numbers on the SDCard reader are missing.. that's no biggie.. more or less the position is the same from the old RPi Zero (non wifi).
I was in the process of hooking the card reader from [mention]prerunnerseth[/mention] to the cartridge slot from a dslite and following [mention]wermy[/mention]'s video video where he shows how to wire the pins on the cartridge slot to the RPi.
Well.. the test pad on the left side (3.3V, green wire in the video) is not there on the RPi Zero W in my possession. I'll attach a screenshot.
Can anyone help me here?
RPi Zero W V1.1
RPi Zero V1.3
Edit: I should point out that on the official Raspberry Pi website, in the schematics page, the Zero W pdf is missing

After feeling miserable for 1 hour after searching on the Internet for an answer I actually turned on my brain and came to your same conclusionVeteranGamer wrote:this may help.....

Thank you very much for the confirmation of the 3.3v on the GPIO
The afternoon ended with the cartridge working fine and retropie booting correctly
I'll post some pictures tomorrow
So satisfying!!!
Cheers!

The promised pictures, wiring to the cartridge reader's pins was nerve wrecking hahaha!
I really thought it won't work.. but when retropie booted I was literally jumping around in my room

He probably uses PreRunnerSeth's PCB for microSD card inside the cartridge (just guessing from the wiring).

Ok someone has to help me out here. I have wired this thing every which way and still cant figure it out. Everything has gotten pretty beaten up since i did it so many times -- Can anyone point me in the right direction?

Uhm.. You're using the original gameboy cart reader, so I can't be sure (I used the ds lite gba cart reader). In my pictures you can see that I used the left hand side pins for the wiring.
What you can do to understand exactly is use a multimeter to check the pins..

Re: [HELP] Raspberry Pi Zero W V1.1 - Test Pads problem
Maybe its a dumb question, but how can i check the pins? On the left side of the cart there are those extra pads that i can check but for the side that actually used the sd card, I do not see how I would be able to check.
