Small rectangular development board with a fingerprint sensor window and UART connector

LORDWORLD

LORDWORLD Rectangle Capacitive Fingerprint Sensor (E) UART 32 development board

SKU CH-67AQ-R6C2Z

Rectangle capacitive fingerprint sensor with UART for STM32 and Raspberry Pi, enrolling and matching prints via simple commands

  • UART connector enables direct connection to STM32 or Raspberry Pi
  • Simple command set removes need for fingerprint algorithm knowledge
  • Commercial algorithm handles enrol, match, image capture and feature upload
  • Capacitive touch window verifies identity with a light touch
  • Integrated processor and sensor in one chip suits compact designs

Rectangle Capacitive Fingerprint Sensor

This Lordworld module is a compact development board that combines a capacitive fingerprint sensor with an onboard Cortex processor. It connects through a UART interface and is designed for integration with platforms such as STM32 and Raspberry Pi. The all-in-one package handles fingerprint enrolment, matching and image acquisition without requiring specialised biometric knowledge.

Makers adding biometric authentication

The board suits engineers and hobbyists building access-control, attendance or identity-verification projects that need a ready-to-use fingerprint solution. Developers who require a different communication bus, a larger sensor area or an operating system driver stack will need to look at alternative modules.

UART interface for host connection

The single specification that decides fit is the UART connector, which dictates how the sensor links to the host controller. Your target platform must provide a compatible serial port and be able to drive the simple command protocol described in the documentation.

Questions about this item

How can I confirm the capacitive fingerprint sensor is operating correctly after connecting it via UART?

After wiring the UART link, send an enrol command from the host; the module returns a success code and stores the template, then a match command on the same finger returns a verified result.

What hardware is supplied with the rectangle capacitive fingerprint sensor and what must I source myself?

The board with integrated Cortex processor and capacitive sensor is included; you must provide a host such as an STM32 or Raspberry Pi plus jumper wires for the UART connection.

Which version of the LORDWORLD rectangle capacitive fingerprint sensor should I select for a UART-based project?

Choose the UART 32 variant, which matches the onboard UART connector and integrated Cortex processor described for STM32 and Raspberry Pi integration.
