Hello you all do you know how to adapt this DELL LATITUDE e 6530 camera module to a usb connector?
Do you have any schematics?
Thanks for the reply
Hello everybody
You can not connect that camera directly to USB, or you'll fry it rather quickly. It needs 3.3V to operate correctly, as it says on the silkscreen itself.
If you don't want to get a voltage regulator, to minimize complexity I would recommend you use two diodes and a 100ish ohm resistor in series. But do never take this as a permanent fix for a permanent project.
Hope you have the original loom that plugged into the motherboard. That way you can easily get the pinout from the following part of the schematic:
Thank you for your reply. I have already found this schematic (dell latitude and 6530). The module must be powered at 3.3 volts, I have the regulator, unfortunately I cannot find the positive pin.
The original connector of the module has 8 pins the last one is nc. It is not possible to tell from the colors. This is the photo of the connector.
Note that you are enumerating that connector backwards in respect to the schematic. The twisted pair should be D+ and D- (2 and 3) but you've got them labeled as 6 and 7. It will make a lot more sense if you flip that around.
CAMERA_VDD (Pin 4) is the 3.3V.
Ignore G1 and G2 on the schematic, they're just the anchors for the connector
I made the connections as you suggested and everything works fine. On the schematic is pin 1 the microphone output?
The module appears to have two microphone capsules ...
Thanks anyway for everything tobbyhush.
CAM_MIC_CBL_DET# is directly connected to 3.3V through a 10Kohm 5% resistor.
DMIC_CLK is the clock signal generated by the audio CODEC (92HD93)
DMIC0 is the microphone output (for both).
It is extremely unclear whether these microphones are analog, digital, or both. The output is supposed to be analog audio, but the clock selects either one mic or the other (during rising and falling edge).
Try leaving DMIC_CLK floating and see if something comes through. If there's nothing, hook it up to either GND or 3.3V. The issue would be if it only sends for some microseconds if there's not a clock present, but I doubt that to be the case. If it was, you'd need to provide that signal yourself.
But don't expect that audio on the USB! The output signal on DMIC0 should be analog, not digital (despite the letter D), so you'd need to hook it up to your microphone input or a preamp.
