This example project shows an example for Mikroe Fingerprint 2 Click board driver integration with Silicon Labs Platform.
The Mikroe Fingerprint 2 Click board is a fingerprint sensor module that allows for easy integration of fingerprint recognition functionality into a wide range of projects. It uses a high-quality A-172-MRQ fingerprint sensor that can quickly and accurately capture and compare fingerprints. The board includes an onboard microcontroller that handles all of the necessary processing, and it communicates with the host controller through an easy-to-use UART interface.
The board also includes some features such as the ability to store and match up to 24 fingerprints. It also includes two onboard LEDs to indicate the status of the sensor. This Click board can be used in various projects like security systems, attendance systems, access control etc and is a cost-effective solution for adding fingerprint recognition to your project.
- EFR32xG24-EK2703A EFR32xG24 Explorer Kit (BRD2703A xG24 Explorer Kit Board).
- Fingerprint 2 Click board based on A-172-MRQ.
The Fingerprint 2 Click supports MikroBus, so it can connect easily to EFR32xG24 Explorer Kit's MikroBus header. Be sure that the board's 45-degree corner matches the Explorer Kit's 45-degree white line.
The hardware connection is shown in the image below:
You can either create a project based on an example project or start with an empty example project.
- From the Launcher Home, add the BRD2703A to My Products, click on it, and click on the EXAMPLE PROJECTS & DEMOS tab. Find the example project with filter fingerprint.
- Click Create button on the Third Party Hardware Drivers - A-172-MRQ - Fingerprint 2 Click (Mikroe) example. Example project creation dialog pops up -> click Create and Finish and Project should be generated.
-
Create an "Empty C Project" for the "EFR32xG24 Explorer Kit Board" using Simplicity Studio v5. Use the default project settings.
-
Copy the file
app/example/mikroe_fingerprint2_a172mrq/app.cinto the project root folder (overwriting existing file). -
Install the software components:
-
Open the .slcp file in the project.

Build and flash this example to the board.
Note :
-
Make sure that the SDK extension already be installed. If not please follow this documentation.
-
SDK Extension must be enabled for the project to install "A-172-MRQ - Fingerprint 2 Click (Mikroe)" component.
The example compares a fingerprint on input to the registered fingerprint and shows a message on the console screen on which input fingerprint is identified or on which input fingerprint is not identified.
You can launch Console that's integrated into Simplicity Studio or use a third-party terminal tool like TeraTerm to receive the data from the USB. A screenshot of the console output is shown in the figure below.
