Reuse Fingerprint Scanner from Lenovo W510 Laptop Answered
I have a Fingerprint reader from a Lenovo W510. The model number of the circuit board is 48.4CU13.011, which seems to be shared by both my Lenovo and another Fujitsu laptop. The fingerprint reader is a spare part, and I thought it could be cool if I could hook it up to a PC by USB. When connected to the laptop in question, it shows up as a USB device: UPEK Touchstrip TCRD4C - USB ID 147e:2016
The chip is connected by an 8 pin ribbon cable to a larger ribbon cable which also connects to the touchpad. Looking at the board under a magnifying glass, it looks like there may only be 4 of 8 pins connected to the ribbon cable connector. The chip on the circuit board appears to be a TCD50 fingerprint reader controller, made by UPEK or possibly Authentec (did Authentic take over UPEK?)
I was hoping someone might have some experience wiring this board up to USB, or could point me in the right direction to figure out what pins go where. I looked for datasheets, schematics, and pinouts without success, but I don't have much experience searching for this type of stuff. I'm pretty handy with a soldering iron, so I feel confident that if I knew which pins went where, I could get a cable hooked up.
