SW M590E not working

Hi, I'm planning to start new project with the SW M590E module. But when I try to wire that with Arduino, It not worked. I mean it not powering up. Can someone please help me to connect it properly and get it to work

if you do a web search for SW M590E or m590e arduino you will get many links

I did. But I couldn't find wiring instructions for arduino.

this shows the connection to an Arduino Mega plus example code

note the level converter or use a 3.3V Arduino such as the Arduino Due

also seen several recommendations to use an external power supply

This is very important. Thank you so much for your Help
