Since they have come back in stock, I bought a Pi 4 2GB and a Pi 4 4GB. the 2GB model had 2 bent GPIO pins and rattled when shaken, so I opened an RMA request for it. the 4GB model has arrived, and it has small solder blobs on the back of the board (see images)
Is this normal or have I just got unlucky with both Pis? I managed to scrape off solder on the first image but they have left a mark on the board.
The 2GB model seems to be completely working and the 4GB one boots to the bootloader but I'm out of SD cards to test it any further. Should I also RMA the 4GB model or am I being silly here?
Thanks.
Can I/Should I just scrape off the leftover blobs?
I didn't know I could boot from USB, thats cool. If It's booting to bootloader it's probably fine though right? I'm replacing an existing 2GB anyway so I'll see soon enough.
I would scrape them off without using much force. Otherwise they can come loose on a worst time possible and maybe short circuit some pins when the board is powered. Probably will never happen if the raspberry is statically mounted somewhere, but you never know when you are going to drop it while powered.
P.S If you are going to run some servers/services off the raspberry do not use regular usb sticks or sd cards. Get a USB ssd or USB to sata or M2 adapter. Some write intensive applications burn through quality sd cards/usb sticks within a year
This Pi will just be a router, later I will run some DB stuff though so I'll get an SSD. I have another Pi I do some intensive Data stuff with and I have a sata SSD for that one.
There where some bits I didn't see before and I scratched the PCB a bit, does this look good?
EDIT: my phone did some weird things to the photo lol
I replaced my old Pi and it's working fine. sadly the heat pads on my argon one have disintegrated in the process lol
