SparkFun FPC2534 Arduino Library

The SparkFun FPC2534 Arduino Library examples demonstrating how to use the FPC2534's main features including fingerprint enrollment, fingerprint template management and navigation over either I²C or UART. You can install the library with the Arduino Library manager tool by searching for "SparkFun FPC2534". If you'd prefer a manual install, you can download a ZIP of the library here.

Supported Boards

The I²C (Qwiic) interface for the SparkFun Fingerprint Sensor - FPC2534 Pro board is currently only supported on ESP32 and Raspberry RP2 (RP2040, RP2350) boards. The I2C Implemention of the FPC2534 device performs a dynamic payload transmission that is not supported by the Arduino Wire library. Because of this, a custom implementation is provided by this library for the ESP32 and RP2 platforms.
