Does anyone here know what you are talking about? Probably not.
Please explain what you are talking about, what the part or circuit is, what it is supposed to do, what are the inputs and outputs. Is this a purchased product? Post a link to data, the vendor, photos, etc.
What do you mean by improve or enhance? What is wrong with the one you have? Which biometric does the lock use?
