Built around the FPC2534 from Fingerprint Cards AB, it handles enrolment, encryption, internal storage and authentication without requiring your host microcontroller to process sensitive biometric data.It is designed for the Qwiic ecosystem, with two Qwiic connectors for solderless daisy-chaining, plus a USB-C connector for direct connection to a computer. Peripheral pins are also broken out to 0.1-inch-spaced headers for breadboarding and more flexible integration.Beyond scanning fingerprints, the sensor supports four-direction navigation with tap detection, so it can also work like a compact touchpad or directional input. SparkFun provides supporting documentation including a hookup guide, schematic, KiCad files, board dimensions, datasheets, a GitHub repository and the SparkFun FPC2534 Arduino Library.Features:Automatically created fingerprint templatesUp to 45 unique templatesEncrypted and stored in Flash memoryOnboard authentication softwareAdvanced security featuresSecure communicationAnti-spoof functionalityFour-direction navigation with tap detectionMultiple communication interfaces*I2C (Default), SPI, UART, and USBSelectable by adjusting the config (CFG1/2) jumpers on the boardLow-profile design with durable matte coating3.3V operating voltage2x Qwiic connectors1x USB-C connector2x 0.1"-spaced PTH headers4x grounded mounting holes (connected to FPC2534 bezel ground)Green scan LEDRed power LEDSpecifications:Sensor: FPC2534Fingerprint templates: Automatically created fingerprint templatesTemplate capacity: Up to 45 unique templatesTemplate storage: Encrypted and stored in Flash memoryAuthentication: Onboard authentication softwareCommunication interfaces: I2C (Default), SPI, UART, and USBInterface selection: Selectable by adjusting the config (CFG1/2) jumpers on the boardOperating voltage: 3.3V operating voltageQwiic connectors: 2x Qwiic connectorsUSB-C connector: 1x USB-C connectorPTH headers: 2x 0.1"-spaced PTH headersMounting holes: 4x grounded mounting holes (connected to FPC2534 bezel ground)Scan LED: Green scan LEDPower LED: Red power LEDI2C requirement: Communicating with the FPC2534 over I2C requires connecting the interrupt request (IRQ) and reset (RST) pins to compatible I/O pins on a microcontroller.Enrolment sampling: 12 samples for accuracySuitable for secure access terminals, hardware password managers, smart locks and other projects that need compact biometric authentication with flexible connection options. **Product Type:** Fingerprint Sensor ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDskUBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--6606fa341b888fc13869eb8c9178df0961695c85/29854-fingerprint-scanner-feature-2.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDs0UBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--8cd23f15594490477d5de936bf3b4f65c205b112/29854-Fingerprint-Scanner-Front.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDtEUBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--b6bbc3fbce32d3e4d8172cb075935ad1353fa169/29854-Fingerprint-Scanner-Scale.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDtUUBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--e841c48bb481a293be049c232ee415c777d2b4d1/29854-action-reshoot-16.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
