#2722: R307 Optical Fingerprint Reader Module


The R307 fingerprint module is a small, low-cost fingerprint sensor that can be used to add fingerprint recognition capabilities to a project or system. It is based on the R305 fingerprint sensor, which is known for its high accuracy and reliability. The R307 module includes an onboard processor that handles the fingerprint enrollment and recognition processes, and communicates with the host device (such as a microcontroller or computer) over a standard serial interface. It is often used in security systems, time attendance systems, and other applications where fingerprint authentication is required.
