A RT3050 PCB
So I removed the components with a hot air rework tool, and once that was done I stuck the board in a scanner. It was still a little hard to see the traces under the silkscreen and mask so I sanded most of it off.
Here’s the board with most of the silkscreen and mask sanded off.
And with most of it still intact:
The backside image has been flipped horizontally so the images can be overlaid.
This SVG contains the layers aligned, and a bunch of the traces mapped out/annotated:
I’ve also been putting a kicad design together based on this chip, you can find the files here:
A few other random images of the original PCB:
Useful datasheets:
I couldn’t find a datasheet for the Zentel A3V28S40ETP-G6 on this board, however it seems to be similar to the M12L128168A:
The crystal on this board seems to be a SMD3225 layout, I guess similar to this part:
AIC809-29PU, RA29P:
EH11A – AZ1117 (LM1117?)
