The flexibility to adapt to the conditions was the fingers, whether it is dry fingers, wet fingers, light texture fingerprints fingers, and old fingers, all have high recognition rate 3. The main application areas: can be embedded into a variety of end products, such as: access control, attendance, safety deposit box 4. The R503 fingerprint module has a built-in algorithm chip 5. The interface line spacing is 1.0mm, and the line length is 20cm. Thread diameter is 25mm, easy to install. Supply voltage: DC 3.3V Working current: 30mA (typ.)
