FPC1020 Fingerprint Touch Sensor Kit

Description

This is a fingerprint touch sensor kit base on FPC1020 touch fingerprint sensor, it is composed with a fingerprint sensor FPC1020 and a control board.

The fingerprint sensor’s mode is FPC1020 from Fingerprint Cards, which has been widely used on smartphones such as Huawei Mate 7. It is based on capacitive sensor technology. It delivers best in class image quality with 256 gray scale values in every single programable pixel. No matter dry, wet or dirty finger, it can read with its 3D pixel sensing technology. The control board is based on an ARM® Cortex®‑M processor, it has a pre-burned program inside for processing the UART commands. Through this board, we can directly drive the fingerprint sensor via serial port. 

This fingerprint sensor kit is easy to use. There is an Arduino code provided that allows us to quickly get started. Also, a Grove cable is comes, so that we can quickly add it to the Grove system.

Hooking up

There are only four pins that need to be hooked up in order to start using this sensor in a project. One for VCC, one for GND, and two data lines.

• VCC           →   5V
• UART_RX  →   Digital 2
• UART_TX  →   Digital 3
• GND          →  GND

Installation

• Download FPC1020.zip
• Unzip, and add to Arduino/hardware/libraries/
