Frequently Asked Questions

What is the operating voltage range for the R307S module?

The R307S Fingerprint Module operates from 4.2V to 6.0V DC. It is compatible with standard 5V microcontroller systems like Arduino Uno. Ensure your power supply can provide sufficient current, with typical consumption under 75mA.

How do I connect this module to an Arduino or ESP32?

Connect via the UART (TTL) interface using the provided 6-pin cable. Wire the module's TX and RX pins to your microcontroller's corresponding RX and TX pins, and connect VCC (4.2-6V) and GND. Use a software serial library if your main serial port is occupied. The module communicates using a simple serial command protocol.

What is the difference between the UART and USB interfaces?

The UART interface provides TTL-level serial communication (3.3V/5V logic) for direct connection to microcontrollers like Arduino, ESP32, or STM32. The USB 2.0 interface allows direct plug-and-play connection to a PC or single-board computer, enabling development and integration without an additional USB-to-serial adapter.

How many fingerprints can the module store?

The module has a high template capacity, supporting storage for up to 1000 individual fingerprint entries. This makes it suitable for applications requiring management of large user groups, such as corporate attendance systems or multi-user access control.

Is any special software or SDK required for development?

Development typically uses the module's documented serial command set. You can send specific CubePilot commands via UART or USB to enroll, delete, and verify fingerprints. Many open-source libraries exist for popular platforms like Arduino to simplify integration. For PC applications, the USB connection often appears as a virtual COM port.
