## Description

**FACE-FINGER** is another FACES kit compatible panel, with a built-in finger-print recognition module inside of it. Similar to the FINGER unit, FACE-FINGER integrated the FPC1020A capacitive fingerprint recognition module and Fingerprint recognition algorithm chip.
<br>
It can identify fingerprint information entrance, fingerprint deletion, fingerprint search, feature extraction for multiple people and so on. The unit can configure the fingerprint recognition comparison and security levels. With FACES panel, you can upgrade the level of Fingerprint management machine with a more complete and enclosed pattern.

Communication Protocol: UART.

>1.EasyLoader is a simple and fast program burner. Every product page in EasyLoader provides a product-related case program. It can be burned to the master through simple steps, and a series of function verification can be performed.

>2.After downloading the software, double-click to run the application, connect the M5 device to the computer via the data cable, select the port parameters, and click **"Burn"** to start burning.

>3.The CP210X (USB driver) needs to be installed before the EasyLoader is burned. [Click here to view the driver installation tutorial](en/related_documents/M5Burner#install-usb-driver)
