Frequently Asked Questions

What is the communication interface of the Grow R503S module?

The module uses a UART interface with RS232 TTL voltage levels (0V/3.3V). It communicates via simple serial commands for enrollment, verification, and deletion of fingerprints, making it compatible with most microcontrollers like Arduino, ESP32, and STM32 without needing additional protocol converters.

What is the operating voltage and power consumption?

The module requires a stable 3.3V DC supply. During active fingerprint acquisition, it draws approximately 20mA. In standby mode with touch detection enabled, it consumes an average current of only about 2µA, making it suitable for battery-powered or energy-efficient embedded applications.

How many fingerprints can the module store and what is the recognition accuracy?

The R503S can store up to 150 individual fingerprint templates internally. It features an integrated algorithm chip designed for a high recognition rate, capable of adapting to various finger conditions such as dry, wet, or aged skin to provide reliable authentication performance in diverse environments.

What are the physical dimensions and mounting options?

The module has a cylindrical form factor with a 28mm external diameter, 19mm height, and a 25mm internal diameter featuring an M25 mounting thread. This allows it to be securely screwed into a panel or enclosure cutout, providing a flush and professional installation for access control panels or devices.
