Fingerprint Scanner - TTL (GT-521F52) SF_Soft Potentiometers There is also an FTDIFingerprint scanners are awesome! Why use a key when you have one right at the tip of your finger? Unfortunately, they\'re often unreliable or difficult to implement. Well not anymore! This great GT 521F52 fingerprint module from ADH Tech communicates over TTL Serial so you can easily embed it into your next project. The module itself does all of the heavy lifting behind reading and identifying the fingerprints with an onboard optical sensor and 32
