It uses a 500 DPI sensor and an effective sensing area of 11×15 mm to capture clear fingerprint images for access control and similar embedded applications.\u003c\/p\u003e\u003ch2\u003ePerformance \u0026amp; connectivity\u003c\/h2\u003e\u003cp\u003eThe module supports USB 2.0 for PC connection and RS232 (TTL) serial for microcontrollers, with a configurable UART baud rate (default 57,600 bps). Capture speed is under 0.2s and verification under 0.3s, with 1:1 and 1:N matching, low power consumption and blue backlight for the sensing window.\u003c\/p\u003e\u003ch2\u003eDeveloper, setup \u0026amp; reliability\u003c\/h2\u003e\u003cp\u003eThe R307S can connect directly to 3.3V or 5V microcontrollers and provides reference SDKs for Arduino, Android, .NET and Windows; user manual and SDK files are available on request.
