Greetings,
I have been trying to find an optical or laser mouse sensor to enhance my project’s dead reckoning capabilities (since sensors that give delta-x and delta-y directly can be far easier and more reliable than encoders and a silly amount of math), but most of them are out of stock everywhere I look! The only one I’ve been able to find is the ADNS-9800 on a website that isn’t even close to a retailer that I trust for these kinds of things (I only really trust Adafruit, SparkFun, and Digikey fully). Is there anywhere I haven’t looked or simply a term I haven’t thought to search under? Or, is it pointless to try to find a special-purpose mouse sensor?
