Where can I get the sensor?

tyjustice - 답글

I second this, for the life of me, I can't find it. Just data specs and how most of the electronics retailers online says it obsolete, specially since Avago got absorbed by Broadcom.

This is helpful up to the point where I need to know where to get the sensor. Where do I get the sensor?

Art Adams - 답글

Any update where to get a new sensor? I just received a device from a friend and it needs to be fixed.

Steven D'Ambrozio - 답글

The easier path would be to install a rotary encoder, and call it a day. If you do find the sensor, you have to code basically a driver for it and print your own pattern.
