I have exactly the same issue, I am also using the Retro PSU with the powerboard and the Pi shuts down after a few seconds.
Also using Veterangamer's component list.
Any ideas appreciated.

I have done a similar project but using a 7inch screen (had to expand the whole unit) and a power brick instead of a power board. Using a Teensy LC with Xinput. Everything seems to work fine on the PC but the Analog sticks only activate if pressed. When pressed they work fine. Otherwise they drift instantly to the lower right. This is on both sticks (using the wii u gamepad sticks and buttons). Happens even when disconnected the click button. On the raspberry pi (RetroPi) The triggers dont work. I have the triggers set to buttons. Should I, could I, have them set up as Triggers but only min and max??

Are you wiring the TX GPIO to the powerboard? That is what keeps the Pi and everything else powered if that is not connected to the powerboard and is also setup in the config.txt the pi will turn off after a few seconds of being turned on.

Figured out the joystick problem, got the click and ground mixed up. Still not able to set up triggers in the main retropi screen but can in emulators but the analog sticks i can only assign up and right. Know of how this could be? On the PC everything works great.

Read an old post last night where the tx pin must be connected to the gpio pin so to keep the board alive. All working now, thanks for your help.

Parts required are:

Dual Fet is : SI4532CDY-T1-GE3
P-Channel Fet: SI2301CDS-T1-GE3
D1: MBR0520LT1G

It looks like the Dual Fet part linked is no longer available. I also tried searching for the 4562 version Helder recommended. Not sure if I need to buy one with that exact model#. Any ideas on where I can get one, or anybody willing to sell me a spare?

Can someone tell me if the link's MOSFET is compatible with T1? https://es.aliexpress.com/item/33057594 ... c64e60[img][/img]

its still about....
i'm sure if you search you'll be able to get the correct ones....



if people are that stuck....
I think I have a few knocking around, I just have to find them
(but i'd suggest searching online first as they are out there, as postage alone is gonna be around £3.50/$5 from the UK)

Thanks helder

I will try later

the truth do not connect it thinking it was not important

I have connected the TX to the GPIO 14 pin of the raspberry and I have configured the /boot/config.txt adding the line at the end.

dtoverlay = gpio-poweroff: gpiopin = "14", active_low = "y"

That shows VeteranGamer.

I give the button to turn on and do the same, turn off the second.

Is there something I'm doing wrong?

Is pin 14 the physical or the bmc that would be pin 8?

P.S.

I already solved it.

I had to connect it to gpio 14, which is 8 in physics, since 14 refers to bcm.

The problem that I had that pin I have broken when trying to desoldar the pins.

Then I used the gpio 15 and it works perfectly.

It is already on.
