Ultra-Slim Round Fingerprint Sensor and 6-pin Cable

DESCRIPTION

Secure your project with biometrics - this adorably tiny, all-in-one, optical fingerprint sensor will make adding fingerprint detection and verification super simple. It's extremely slim, with a plastic casing that can be glued or panel mounted into any enclosure! There are some embedded blue LEDs that light up the outer casing when the sensor is waiting for finger touches.

These modules are typically used in safes - there's a high powered DSP chip that does the image rendering, calculation, feature-finding, and searching. Connect to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash, and search. You can also enrol new fingers directly - up to 80 fingerprints can be stored in the onboard FLASH memory. It also comes with a 6-pin Molex-style 1mm pitch connector, which you can easily cut off and solder directly to the wires.

With both an Arduino library and CircuitPython library available you can get running quickly and easily in under 10 minutes

Arduino Library

CircuitPython Library

Use this pin-out to connect to your microcontroller, and then use our library to interface over UART pins. Please note this sensor uses 115200 baud rather than the 'standard' 57600 used by many other sensors, so you'll need to update the examples to 115200 baud for the sensor to respond

• Black to GND
• Yellow to Microcontroller TX (data out from microcontroller)
• Green to Microcontroller RX (data in from microcontroller)
• Red to 3.3V VIN
• White to IRQ (can leave disconnected)
• Blue to 3.3V VCC (can leave disconnected)
