Does the 5.8GHz Microwave Radar Module have any visible LED to show its working?

I am using an Arduino Mega and I have been using the 10.8 Ghz MW Doppler board and seems to be fine, i have just bought a 5.8GHZ board and hooked it up and tried to use the DFRobot_Microwave_Radar_Module library to set it up, every call returns error. I am confident that the serial port and pin outs are correct. Is there any LED's on the board to show its working, like the 10.8 GHZ model. I can't see anything, it acts like its DOA and I can't think how to prove its not.
Thanks in advance,
Rod
Working voltage range: 4.5~5.5V
Please check the power supply to the sensor.
Are you using the sample code?In the sample code, RX and TX are defined as D4 and D5 pins.
SoftwareSerial softSerial(/*rx =*/4, /*tx =*/5);
Please try to connect according to the wiki. If there is no data, please exchange TX and RX wire.
The O pin of the sensor can output the signal. You can use meg2560 to try to read the high and low levels of this pin.
Could you pls upload the connection diagram or the code? Thanks for more details.
