Hello,i use the wermy's tuto for build my gbz but i use a bw screen and not adafruit. I want to know, when i soldering wires in the board, the screen is in 5v, can i just connect my rasp pi to screen and connect my charger lipo with my battery to raspberry pi to test my screen or i must put a booster volt between the battery and screen? I ask this question because i dont use the same screen so i dont know if is enough with my method without booster. Thanks

Is your screen listed here?

Some screens will run fine on 5v or 3.3v. While other run off 12v and may need modification to run on 5v. (You may need a booster, or maybe not)

You can see a quick guide here how to connect a screen to a pi zero.

I think its the variant 7. I didn't test, i ask this question because im afraid the battery exploding or burn do you think it can be dangerous if i test the connexion?

It will be fine. The battery will not explode.

Ok thank you lol

Do you think its ok? I can connect without problem? I think i soldered like a pig

It's not the cleanest, and it looks pretty messy on that screen board. (Did you remove the little chip?) It looks like a giant blob of solder, that should be cleaned up and then it should be fine to test. Worst that will happen is it won't turn on. Then you can troubleshoot from there

Yes i removed the chip, ok i will test and if it don't work i will do again the solder

Des news de ton ecran nico ? ça marche ? ^^

Non j'hésite à tout brancher, j'ai pas confiance avec la batterie. Je suis pas rassuré :/
