LORDWORLD

LORDWORLD High Precision Capacitive Fingerprint Reader (B) Module development board

SKU CH-J3G6-0HM95

Capacitive fingerprint reader module with UART and USB interfaces for enrolment, matching and image processing, plus example code for Raspberry Pi, Arduino and STM32

  • Simple commands eliminate fingerprint expertise
  • Commercial algorithm delivers stable fast matching
  • Light touch sensing without pressure required
  • Dual UART or USB communication options
  • Development resources for Raspberry Pi Arduino STM32

LORDWORLD Capacitive Fingerprint Module (B)

This development board integrates a high-precision capacitive fingerprint reader for enrolling, matching and searching fingerprints. It targets makers and engineers building biometric access control, attendance or identity-verification projects on embedded platforms. The module handles all fingerprint algorithms internally, so no specialist knowledge of fingerprint technology is required.

Simple command interface with UART or USB

Control the reader through a compact command set over either UART or USB; no low-level algorithm work is needed. Rich development resources including command documents, tools and example code for Raspberry Pi, Arduino and STM32 accelerate integration. The only common pitfall is wiring the chosen serial interface incorrectly, which prevents communication until the TX/RX lines or USB enumeration are corrected.

Dual UART and USB communication interfaces

The board exposes both UART and USB ports, letting you select the link that best suits your host controller. This dual-port flexibility is the single specification that determines whether the module fits your existing hardware design. Buyers whose host offers neither a spare UART nor a USB host/device port will need a different fingerprint solution.

Highlights

  • Simple commands eliminate fingerprint expertise
  • Commercial algorithm delivers stable fast matching
  • Light touch sensing without pressure required
  • Dual UART or USB communication options
  • Development resources for Raspberry Pi Arduino STM32

Questions about this item

How can I verify the LORDWORLD fingerprint reader is working after connecting it?

Send a simple command over UART or USB; the module returns a status packet and the LED indicates a successful capture without needing to press the sensor.

What comes in the box with the LORDWORLD High Precision Capacitive Fingerprint Reader (B) Module and what must I buy separately?

The development board itself is included; you must supply a host such as a Raspberry Pi, Arduino or STM32 plus the appropriate UART or USB cable.

Which version of the LORDWORLD fingerprint module should I choose for my project?

Only the (B) variant is listed, offering dual UART and USB ports plus 32 Kbyte fingerprint storage for enrolling, matching and image transfer.
