If you use a TTL usb adapter, yup:)

Connect the RX and TX lines off the TTL usb adapter to the EZ-B plug and voila

Go to Start menu -> Devices and printers.

At the bottom, you should see a 'USB COM port (COM...)'

Niek ----What is the part number or link for the USB->TTL adapter you got from Sparkfun?


Do you need to also hook up the USB->TTL adapter GND to the EZ-B GND? Or are you only using the Tx and Rx?

You can use DEV-09716.

Connecting ground is necessary, you can see how i connected mine in my omnibot video part 2 at (1:35):

Thanks Niek! I appreciate the help.

So the Sparkfun board Rx goes to Rx on the EZ-B and the Tx goes to Tx on the EZ-B and GND to GND.

Will I need to use 3.3V or 5 V?

Niek,

Did you have any problems, or have to make any modifications to the Sparkfun Board you recommended? I am ready to order it now but I read through the comment section and it seems many people have had issues with it.

9716


Thanks,

Rex
