Small round development board with central fingerprint sensor window

LORDWORLD

LORDWORLD Capacitive Fingerprint Sensor (D) 360° development board

SKU CH-E2CV-1SBP3

A round capacitive fingerprint module with 360° verification, UART command control and on-chip sleep mode for low-power IoT projects

  • Simple UART commands eliminate the need for fingerprint expertise
  • Commercial algorithm handles enrolling, matching and image acquisition
  • Capacitive touch enables fast 360° verification
  • Integrated processor and sensor fit nail-plate sized designs
  • Embedded human sensor sleeps until touched for low power

Capacitive Fingerprint Development Board

This LORDWORLD board provides a complete capacitive fingerprint sensor module for IoT edge development. It integrates the processor and sensor into a single compact chip that accepts simple UART commands for enrolment, matching, image capture and feature upload. The round collecting window supports 360 degree touch verification without requiring specialised fingerprint knowledge.

Makers Adding Biometric Access

The board suits engineers and hobbyists who need a ready-to-use fingerprint subsystem for locks, safes or attendance devices and prefer command-based integration over low-level sensor tuning. It is less appropriate for projects that demand an optical sensor, a larger scanning area, or a different communication bus such as USB or SPI.

Sustained Operation Behaviour

An embedded human-detection circuit puts the processor into sleep mode until a finger touches the window, reducing average power draw during long idle periods. On contact the chip wakes instantly and performs verification, so repeated authentications over hours remain responsive without continuous active current.

Questions sur cet article

What host interface does the LORDWORLD capacitive fingerprint sensor board use for communication?

The board communicates over UART using simple command strings, so any microcontroller or single-board computer with a spare serial port can drive it.

Will the 360° verification work if I mount the sensor behind a thin plastic panel?

Capacitive detection requires direct finger contact with the collecting window; a non-conductive cover will prevent the sensor from reading a print.

How can I confirm the module is operating correctly after wiring it up?

Send an enrolment command over UART, touch the window, and verify the board returns a success code plus the stored template ID.
