Hey,

I've tried my brand new Tinkerboy power switch I received on last friday. Well, it's a big fail :cry: :cry:

I need to know if I'm wrong using it ! I tried to simply solder two wires from the powerswitch to the PP2 and PP5 (I tried on the GPIO too) of my pi 3A+, but when I plug the alimentation (raspberry 3 official one), I just see the starting screen
this one :
SpoilerShow
Image
and then it reboots looping indefinitely on this screen...

Here are some pictures (sorry for the bad quality) :

So hypothesis now, is it possible that my soldering points are really bad ? Is it a wrong way to use the powerswitch ?

(I know it is not the initial point of the post but I will go to battery monitoring, once everything is clear to me about this powerswitch)

.

Did you connect a battery when you turned it on? Make sure the battery has enough charge too.

The "rainbow screen" indicates maybe a corrupt sd card or incompatible retropie image.

Hi Tinkerboy,

Thanks for your answer, my image launches perfectly if I plug the alimentation in the pi directly without the powerswitch. And I tried without any batteries cause I didn't receive mine yet.

I have 26AWG wires for 5v and GND (can the issue come from the wires ?)
It only works with a battery plugged in ? or should it work the way i did ?

You need to connect a battery for it to work properly.

Hey !

I'm coming back with more time and new questions :?

I already burnt a raspi 3A at te start of this project so I'm afraid of everything now, I plugged things this way :
SpoilerShow
Image
When I switch on the raspberry never starts and allways stays at the red light state and nothing happen on my HDMI TV
SpoilerShow
Image
I need to add that when i measure (with the switch off) at the JST between battery and tinkerboy powerswitch I get near 4V (I assume that it means the battery is charged ?)

And the main question is why nothing happened for the raspberry ??

If someone knows, I would love getting some help !

sounds like a bad sd card or the wrong retropie install. try installing a fresh image from https://retropie.org.uk/download/ for the pi3

if you get a red light on the pi, then its getting power, but if you don't get a green light, then it's usually something with the card.

Was like "hey i'm not stupid, it cant be that..."
Sd cars slot empty...
Then "oh fuck... What a shame" :shock: :?

Everything's ok with sdcard inside, you're right, totally !
Sorry for that :roll: thanks again, and let's go further now ! :)

(a way to trigger software shutdown before cutting the power), Helder's doesn't. But, you are correct, Tinkerboy's switch does not have the battery monitor built into it (Helder's does).
yes exactly, I bought an ADS to monitor the battery and this is my next step now ;)

Thanks everyone and see you later ! (probably I will face new problems... :roll: )
