I tested my screen with 3,3Volts instead of 5 Volts. Built-in SD card didn't work. Power consumption didn't change.

Have the two people here with the same wrong LCD the same appearance?

It is not so bad, but it is not good.

The SDCard connections on this screen are wrong.

The value of the 3 resistors I have on the TFT PCB are 1Kohm.

But the problem seems to be the connection to the SDCard. They are different between my sreen and your screen.

I attach a Jpg file with some numbers on the SDcard Pins.
Pin 1 is connected to R1
Pin 2 is connected to R2
Pin 5 is connected to R3
Pin 7 is connected to MISO

On your Screen
Pin 2 is connected to R1
Pin 3 is connected to R2
Pin 6 is connected to R3

This means that the SDCard connections on my screen are probably wrong.

Next week i will try my screen with 3,3Volts instead of 5 Volts. I hope the built-in SD card will work.

Ili9341 TFT display's built-in SD card does not seem reliable (search on the internet). We are two with the same problem and need to use an external SDcard reader.
Another problem is about the dimension of this screen. Mine is shorter than the one you show on the Wiki/Build. This mean that it's impossible to fit a unique metal or 3D case.

Aliexpress or amazon are not reliable supplier for this screen. When we order a Ili9341 TFT, we do not get the same product.

The best case would be to define 1 reference for the screen and 1 reference for the  SD card reader(or micro Sd card) from a trust supplier (mouser, ...). I don't know if it's possible.

I have try 0.92 firmware. The Outputs are OK.

My  SDcard reader works with a micoSd card Sandisk Mobile Ultra 8GB Class 6. It doesn't work with SD card Kingston 8GB class4. It also doesn't work with a very old SD card SimpleTech 128MB.

I have try the SDCard reader from the screen, the SDcard become hot very quickly and the screen was black or White, didn't remember.

When working with firmware 0.91 I can't get the SDCard to work from the sreen, so I installed a new SDcard reader, but it doesn't work.

I look at https://github.com/Ixox/preenfm3/issues/3, install firmware 0.90 and now  the new SDcard reader work fine.
I didn't try the SDCard reader from the sreen.

Firmware 0.91 solve the output routing issue, but now the SDcard doesn't work.

Firmware 0.90 doesn't solve the output routing issue, but the SDcard work.

You can install 0.91 to fix the output routing issue.

Thank you, problem solved

i need to configure Audio output like this :
1  - Sound 2 => Output Audio 1

3  - Sound 4 => Output Audio 3
4  - Sound 3 => Output Audio 4
5  - Sound 6 => Output Audio 5

I do not use any SD card. I just start to play with PreenFm3.

The Screen is https://fr.aliexpress.com/item/4001135326039.html?spm=a2g0s.9042311.0.0.4eca6c37SK8ZDM
But i'm not sure if I order  the same screen today, I will get the same screen I got few days or weeks ago. The size of the screen seem to be between 2.4'' and 2.8''.
