Onboard usb connector for MS2!
 

Found this the other day and decided to order a couple.
They have a FTDI chipset so should work perfect for MS2 and are a lot easier than messing with converters!

1) They are expensive.
2) In some cases, I couldn't load the MS2 firmware through those. I had to piggyback a serial port connector.
3) If your OS happens to dislike the FTDI driver, your are done.
4) The port is a little tight; I had to convince customers to really give the cable a good push until it makes a click.
5) Can't be used with bluetooth converters
6) A little sensitive to RF noise; won't work well if you have Low-Z injector drivers on the V3.0 board, lots of comm drops.
7) Some were DoA; good luck getting a refund on an EXPENSIVE component.

Well, that's not good :(
I have a couple of them in 5V level and some in RS232 level so I'm gonna test both out.
Which ones did you use?

RS232 level.
