Hi!
I'm new to Arduino! I'm learning the basics yet! Please help!
Can I use "USB To RS232 PL2303 TTL Converter Adapter For Aurdino Nano Raspberry Pi" (has 5 pins) as a FTDI for data transfer for Arduino LilyPad (LilyPad 328 Main Board ATmega328P 16M for Arduino)(has 6 pins)?
Or I can use only FT232RL for this purpose?
Mix up during parts ordering! 
TiA!

Yes I would expect you can.
Only thing you might have to be careful with is the signal levels. A raspberry pi is a 3.3V device and it might not like 5V on its inputs (if your USB-to-TTL cable uses 5V signals). In the same way, the USB-to-TTL driver can be a 3.3V device and might not like the 5V signals generated by a Nano or LilyPad.
The specs of the USB-to-TTL device might clarify.
PL2303 TTL Converter Adapter
I had several of those (clone) PL2303 based USB to TTL converters. After a Windows 10 update they quit working and I had to replace them all. I was not able to find a driver for them. Apparently the Prolific company changed something in the drivers so that clones won't work. If you can get a driver that will work you can use them, but since there is no DTR signal to auto reset the part that you are programming you will have to do the reset manually.
Yes, you can use it. It is feasible for data transfer. However, it has no the DTR led out on header so it is not good for sketch uploading via serial line.
Thanks for the quick responses!
Which pins should be connected and which can be left out without connecting to the LilyPad?

I used them for years to program stand alone Mega328 projects. It can be tricky but you just have to manually reset the processor at the right time during the programming (uploading) process (right when the IDE first says uploading).
Can Someone help me with the connections?
