I have a SEN0348 connected to an Arduino Uno R3.

 

I've connected it to 3.3v as per the instructions @ https://wiki.dfrobot.com/Capacitive_Fingerprint_Sensor_SKU_SEN0348

 

RX is connected to pin 3

TX is connected to pin 2

 

The IRQ is connected to 3.3v as well.

 

I've installed the DFRobot 1.1.0 library via the Arduino IDE, and loaded getDeviceInformation.ino.

 

No matter what sketch I load, it hangs on fingerprint.begin(). 

 

Is the sensor defective?
