whiteeeen FPM10A FPM10 Red Light Optical Fingerprint Reader Sensor Module 4 Pins for Arduino Mega2560 UNO R3

• With this fingerprint module, you can easily add fingerprint-related biometric applications to your projects. This is an exciting news, you do not need to learn professional fingerprint recognition knowledge, complex algorithms, all you need to have this fingerprint module. Simple module connection, rich cable, can be connected with Arduino, Raspberry PI, 51, AVR, and almost all common platforms, chips. All you need is for your platform to have an idle TTL serial port (3.3V or 5V level). The module uses TTL serial port communication, only 4 cables (red: VCC (5V-3.6V), black GND, RXD yellow (need to connect to TXD end), TXD green (need to connect to RXD end)). FPM10A optical fingerprint sensor, using stable optical acquisition structure, fingerprint acquisition, internal integration algorithm, can achieve fingerprint acquisition, comparison, 1 to 1, 1 to N search, storage and so on. Can store up to 1000 fingerprints (0-999), the product is mature and stable, has been available for more than 10 years, tested and stable in a variety of environments. The module has a self-check function. When the system is powered on for the first time, the fingerprint module blinks. In order to determine whether the module is working properly, very convenient. At the same time, we provide professional technical support, no matter what problems you encounter, you can contact us through the station letter, we will answer your questions in the first time. Each module comes with 3 cables, 1 male head, 1 female head, and 1 bare line for you to weld, the greatest degree of convenience for you to connect, have it, let your favorite project add fingerprint recognition function.
