The GT-NUCL1633K1 is a compact, state-of-the-art fingerprint sensor from the renowned brand, Sparkfun. It is designed by ADH-Tech, offering extensive power efficiency and versatile user adaptability. The sensor allows for 360-degree rotation, ensuring optimal performance without compromising on design. It even functions effectively under challenging conditions, such as when a finger is damp.This product seamlessly integrates an optical sensor, a light source, and touch under a glass cover. This integration allows for instantaneous high-resolution fingerprint image capture. The images are then rapidly outputted through the high-speed SPI interface to the MCU for recognition algorithm.Equipped with advanced optical technology, press instructions, a durable structure, and high ESD immunity, the GT-NUCL1633 sensor offers designers a reliable and highly functional sensor for products requiring fingerprint recognition functionality.Package Includes: * GT-NUCL1633 Fingerprint Sensor * 6 wire UART Interface Cable Key Features: * Under Glass Sensor Positioning (No ESD concern) * Supports an additional 2mm of cover glass if needed * Enables wet finger recognition * Ring of the device illuminated by an indication LED (green) * Matching functionality embedded in the device * 3.3V Supply Voltage * 216 x 216 pixel array * 1024 Grayscale Image Quality * 30 Fingerprint Storage Capacity * UART Interface (115200bps Baud) * Operating Temperature from 20°-70°C * Dimensions * 7.1mm Height * 21mm Outer Diameter * 19mm Inner Diameter The GT-NUCL1633K1 is perfect for those seeking a reliable and efficient fingerprint sensor for their projects. Its advanced features and compact design make it an ideal choice for a variety of applications. https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-01-23 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-09-27 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-10-02 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-10-10 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-10-11 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-10-17 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-10-24 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-10-26 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-10-31 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-11-02 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-11-04 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-11-09 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-11-14 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-11-19 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-11-22 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-11-27 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-12-02 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-12-05 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-12-13 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-12-21 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2025-12-24 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-01-06 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-01-12 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-01-23 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-01-25 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-01-28 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-01-31 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-02-02 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-02-05 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-02-10 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-02-21 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-03-05 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-03-10 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-03-14 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-03-21 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-03-26 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-03-28 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-04-12 https://elecena.pl/product/27748798/sparkfun-fingerprint-sensor-gt-nucl1633 2026-04-17
