Highly recommended for locks
Replaced an old RFID system with this fingerprint module. The security upgrade is noticeable, and the power consumption is low enough for battery-operated locks.

Excellent value for embedded systems
Used this for an office access control system. The small form factor fits perfectly behind standard faceplates. False rejection rate is very low after enrolling users properly.

Fast response time
The sub-second verification claim is accurate. My users love how quickly the door unlocks. The capacitive touch feels premium compared to optical sensors I've used before.

Solid performance, good support
Works well with STM32 microcontrollers. One star off because the sample code provided was for a different voltage level, but technical support clarified it quickly.

Reliable but needs careful calibration
Good sensor quality for the price point. Had to spend some time tuning the threshold settings for optimal performance in low light conditions, but once set, it works flawlessly.

Perfect for custom door lock projects
Integrated this module into a smart home prototype. The UART communication is stable and the SDK documentation made integration straightforward. Recognition speed is impressive even with slightly dry fingers.
Q: What microcontroller interfaces are supported?
A: This module primarily supports UART TTL and USB 2.0 interfaces, making it compatible with most standard microcontrollers like Arduino, ESP32, and STM32.
Q: Does this module support wet finger recognition?
A: The FPM383C has basic water resistance, but performance may degrade with excessively wet fingers. We recommend drying fingers slightly for optimal accuracy.
Q: What is the warranty period for bulk orders?
A: Standard warranty is 12 months from the date of purchase. For bulk orders over 500 units, extended warranty options up to 24 months are available upon request.
Q: Can I enroll multiple fingerprints for one user ID?
A: Yes, the algorithm allows storing multiple fingerprint templates (e.g., left and right index fingers) associated with a single user ID for convenience.
Q: Is there an SDK available for Linux?
A: We provide a C-language SDK that can be compiled for Linux environments. Python wrappers are also available via our GitHub repository.
