I salvaged a small webcam and microphone board from an old laptop that I had lying around. I’d like to use it in some smart mirror project, but I’m having a hard time finding documentation on how to interface with it and wondered if people here knew some more.
The circuit board is identified as FE03FF-99. Googling that shows result to buy the spare part, but I found no documentation, no datasheet, no diagram, no DIY project that hacked this particular model. I found some other webcam board where the person just had to attach a USB cable as the 4 pins they had were simply USB (or 5 pins with two GND). My board, however, has 5 pins, and I don’t know how to identify these. Is it USB ? SPI, UART, I2C ? These pins connect to a cable that merges with the screen’s cable and goes directly to the laptop motherboard.
I identified pin 5 as GND, but that’s about it.
So I tried to identify the IC chips on it. There’s two big one. The first one is a 25L512OIG from MX, which doesn’t yield a lot of result online. I couldn’t find any datasheet.
The second one, I couldn’t clearly identify either. Probably some kind of micro-controller.
What could I do to identify the pins further ? I’m afraid to damage it if I give it 5V randomly when it expected 3.3V (or other). Any help would be greatly appreciated !
Here’s a link to full res pictures. I attached some lower pictures for posterity !
