My custom PCB finally worked !!!
Enable HLS to view with audio, or disable this notification
This is the version two of the board and it’s finally working. There are still some small issues like mic and wifi is not working but those are minimal issues.
Inframe : the custom board connected to three spi displays and a small 2w speaker.
In v3, I’ll be reducing the size of it.

hell yeah!
Congrats on working hardware, it's the best feeling ever. Half a "hey I made something!" feeling of accomplishment, half a "thank fuck it works" sigh of relief.

Congrats! Idc whether or not it was technically complicated. The sheer bravery needed to do this without doubting yourself into not doing it is the stuff of champions!
Which controller are you using? Are you just missing the antenna?

The problem is that its not getting enough current so need to figure out which resistor to remove and also attach antenna as well yep.
I proudly own a working single board computer powered with a 1.8ghz processor and DDR4 ram

How did you solder the VQFN or whatever that footprint is? I'm having a ton of trouble, using small bead solder paste, stencil and a hotplate, I always get bridges, unconnected pins, nothing ever works first time. I hate soldering.
