The Grow R303 Fingerprint Module integrates a high-resolution optical sensor and a dedicated processing chip for reliable biometric authentication. It captures fingerprint images with a resolution of 508 DPI across an effective acquisition area of 11 x 15 mm, ensuring detailed feature extraction for accurate matching.
Designed for low-power embedded applications, the module operates from a 4.2V to 6.0V DC supply and communicates via USB 2.0 or a 3.3V logic-level UART serial interface, making it compatible with a wide range of microcontrollers (Arduino, ESP32, STM32) and single-board computers. Its onboard algorithm chip handles image processing and template matching, offloading computational tasks from the host system.
