What is the correct AC input voltage for US and foreign machines?
One thing to keep in mind is also the difference in the frequency in your home market vs foreign products. I used to live in the US and when I came back to Europe I brought my...

I marked Brian's answer as "the answer" but I just wanted to point out that all of you helped me out greatly. I tested the cable - it still works and I am now able to talk to...

Help me understand this circuit (3v3 to 5v UART)
I'm still confused as to why my cable is called TTL-232R-3V3 if it has nothing to do with RS232!?   On the packaging it says: TTL-232R-3V3 USB to TTL Serial Cable (3v3)...

Help me understand this circuit (3v3 to 5v UART)
If RS232 is 7-12V, why is my cable called TTL-232R-3V3   What does the 3v3 imply? Which part of my setup is incompatible?   I have   Computer - USB port - Cable -...

Help me understand this circuit (3v3 to 5v UART)
What does the "slash 2" on the wire mean, that it's binary?   So in my case it should be 3v3 because that is the Vcc.    Back to the schematic - does that mean that...
