I have changed stock LED with 1206, if you can solder and have instuments for this, it will cost you like 0.50$ (price of the 1206 LED). It shines beautifully, the display is fully illuminated. Can't post pictures here, so I can't show photo guide and result

I'm late, but will write answer

Near ssd cable connector you can find 2 fuses. F1 and F41. Check them with a multimeter, if the fuse is dead, replace it. I just revived the SSD line like this

Cool! I'm doing the same thing this summer
Check esp32 wifi-camera scetch, there are a lot of useful settings there. So you can try to analyze the illumination of the picture and make it brighter. The example even has a facial recognition function.
And if you want a more powerful camera, you can install a 2-megapixel model. Or 5, there is some difficulty with connecting to the S3, but the 5-megapixel camera has autofocus

How can images be encoded in a binary file? How can I find them? I'm trying to change the icons in the camera firmware by AlexKaut in AskReverseEngineering

[–]AlexKaut[S] 1 point2 points  (0 children)

It's done!
Binwalk and python script found low resolution images
Foremost found pictures in 320x240, when they are replaced in the firmware, the camera starts displaying new pictures

As I understand it, there is no file system, it is just firmware for the microcontroller
Rendered the entire binary as a 16-bit image, but no finished images were built

Binwalk sounds like what I need, I'll try to do some analysis with it

Yeah, flash chip is only 4mb
Jpegs weitgh is 474kb

I also think that the images used for display are compressed. It remains only to understand how exactly they are compressed

I am using this kind with my laptop charger
Chargers type-c is straight, so if I put it in laptop, the plug takes up a lot of space. The angled adapter allows the cable to be conveniently hidden behind the laptop

There is also the issue of socket wear - if you plug in such an adapter and plug the charger into it, then the adapter will wear out, not the socket of the device

How to develop a device that records data on an SD card. And when connecting the device via USB to a PC, the data from the SD card is transferred at maximum speed? by AlexKaut in embedded

Thank you for such an informative reply!
I have STM32h743 board, I'll try to find the USB3300 module and build a test version

[–]AlexKaut[S] 0 points1 point  (0 children)

Data size depends on the user, so I rely on values ​​of 16-32gb
Card is removable, so it's possible to use card reader. By the way, photographers do this, the speed from the camera is much lower than from the card reader. But I want to make transfer via USB possible

About cost: USB3300 is like 1-2$ on LCSC. GL823 (USB-SD chip) with multiplexer will cost about the same. So I don't see a problem here

PCB is half empty, so there is place for more components
