Exceeded expectations
Used this to replace a keypad on my workshop door. The circular sensor area is intuitive to use, and the feedback from the RGB ring makes it feel very modern. Setup took less than an hour.

Fast and Reliable
I tested this against three other modules in this price range, and this one had the fastest recognition speed. The RGB lighting is customizable which is a huge plus for aesthetic builds.

Solid build quality
The semiconductor surface feels durable. I've enrolled ten different fingerprints and the false rejection rate is practically non-existent. Highly recommend for prototype development.

Perfect for DIY Security Projects
This module is incredibly easy to integrate with Arduino and Raspberry Pi. The RGB light adds a nice professional touch to the enclosure, indicating status clearly. Recognition is fast and accurate even with slightly dry fingers.

Great sensor, documentation could be better
The hardware quality is excellent and the circular induction works smoothly. However, the sample code provided was a bit sparse. Once I figured out the UART commands, it worked flawlessly for my smart lock project.

Good value for money
We bought five of these for our student robotics competition. They all performed consistently. The only minor issue is that the RGB brightness is quite high at night, but that can be managed via code.
Q: Is this compatible with 5V Arduino boards directly?
A: The module operates best at 3.3V. If using a 5V board like the Arduino Uno, we recommend using a logic level converter for the TX/RX lines to ensure stability.
Q: What happens if the finger is wet or dirty?
A: While the semiconductor sensor is robust, performance may decrease with excessive moisture or dirt. We recommend keeping the sensor surface clean and dry for optimal recognition rates.
Q: Does this module support multiple fingerprint storage?
A: Yes, this module can store up to 100 unique fingerprint templates in its internal flash memory.
Q: Do you provide a Python library for Raspberry Pi?
A: Yes, we host a basic Python library on our GitHub repository specifically designed for Raspberry Pi GPIO and UART integration. Check the product manual for the link.
Q: Can the RGB light colors be customized via code?
A: Absolutely. You can control the RGB LED color and breathing effects by sending specific hex commands through the UART interface.
