I have Fingerprint module from old sony laptop... Can anyone help me to get the pin breakouts ? Answered

This fingerprint reader module is from hannstar-j  m.b. which I extracted from a old sony laptop (I dont have SN or model no).  This module has weird type of 10 pin socket connector. Can any1 tell me the pinouts for it....? I want to connect in to my new laptop via USB or PS2. I tried to connect it with same type of connector from BT module but it didn't connect. Please help....

I'm afraid few can help you. There is very little to find about this except that it is a sony part called the IFX-530.

Not even sure if it is a USB device to begin with. It has a unidentifiable reader, some external parts and a eeprom. nothing that suggests it is a fully integrated usb reader.

Hmm. i see you found a image showing that it is indeed a USB device. You could try to reverse engineer the pinout from the module.

Look closely at the connector and the pins attached to it, Note down which ones have a trace going towards something else and what it is. Which is connected to the big planes and so on. If you are lucky and the module is indeed merely a USB device you will find 3 traces coming out of the connector going to other parts and other pin(s) being connected to the large Plane.

If you know which pins are connected you can try to figure out which pin is which. The pin(s) connected to the large planes is often the GND, the one going directly towards the eeprom and the reader is probably the VCC and the 2 left are than D- or D+. in which case you can try to figure this out by trial and error.

alternatively see if you can get a close-up image of the connector on the module and show it to us, maybe i and/or others can then see what pins are connected and perhaps determine which pins are which.

You can try to reverse engineer it, look up the part numbers, trace out the traces, etc. If you can figure out the power pins at the very least you can then try powering it with 3V and see if it does anything, you would probably need a scope to probe the other pins.

Oh... after some googling I found that FP sensor has USB bus....
