USB -FTDI 232RL- RS232 Converter

[iBruno]

Hello 

I am having troubles, to find the decent cable/interface to get this working properly!!

I bough converter USB -FTDI 232RLChip- RS232, Converter.
IS giving me 6.60v Output.. and I needed 3.3v. Electronically, what can I do, to adjust for the correct Voltage?

My phone didn't fry, besides I got connection! when I load the hello world or layer one, is not completing the task! I believe is because of the amount of power.

If you know a cable that works decently, let me know :-)

Big thanks to whole community.
