I'm making a project using a Picaxe microcontrollers but I don't have a serial port and I don't want to an adapter, so I'm asking what do I need to convert USB to Serial? I search the web and I found some FTDI chips but I don't know if they can provide the right amount of voltage to the circuit, due to the special voltage levels used by RS232, can they provide that voltage?

Thx...

 

You'll need a transceiver... I am sure FTDI has some examples on their website, Just look at their eval modules datasheet for example schematics.

Also look here:

They have a USB interface.

 

Thank you a lot... Already found what I need with your help...
