I have a couple of defective pi4s that I have managed to destroy by using the wrong power supply.
Since I want to learn how to desolder and solder surface components, I went to purchase an infrared heater, as well as a hot air soldering station.
First I replaced the DA9090 ic, and got a boot on the pi, but no usb, eth or wifi/bluetooth.
Replaced the VL805-Q6 usb controller and BCM54213P eth controller, and now have both usb and wired network.
Then there was wifi/bluetooth, which was a disaster, since the wifi ic dropped from the wacum tweezers and made a mess of the components around this chip.
I have searched everywhere for component locations, but have not been able to find any info, or pictures since they are located under the metal cover
Does anyone have a diagram or photo of this part on the pi4 ?
