I have broken my usb port on my arduino mega, I believe I may be able to use a ftdi/usb basic break out board, can any one vaify this and possibly explain how to tie in this module ?
note: I tried to resolder it, turned out quite well until I got to the last solder joint and the ciruit trace lifted, its pretty much non repairable now.
I understand it is the USB connector you have problems with...
To replace it with another USB/TTL break-out board is a little bit of overkill, but can be the easiest way.
There are some China made boards that have a CP202 or similar rather than a FTDI chip. They come with a driver on CD and work with Windows XP at least. On the plus side they produce a reset strobe rather an DTR signal.
This is handy as they can directly be connected to Arduino's RX, TX, RESET, 5V and GROUND.
Connecting other breakout boards need a 4.7nF to 100nF capacitor between DTR and RESET for auto reset.
Thanks richard and deSilva for responding I really do appreciate it!,
the break out board is a DEV-09716 ftdi basic break out board (5v), from spark fun electronics, supposedly it is compatible with arduino and arduino compatible controllers, I guess Iam just not sure how to connect it as there are multiple ports on the controller, its actually
a seeeduino mega controller, any help you could give would be appreciated, Note: this is my first post so forgive me if I have not
created this post properly or not followed the right protocol.

What did you resolder? If you can remove the existing FTDI chip, I believe this will make things significantly easier.
thanx for asking cmiyc,
well the usb connector broke off my seeduino-mega, I tried to resolder it, but the circuit trace lifted, so I am attempting to regain
my usb connection to my pc by connecting a ftdi breakout board
to one of the other available communication ports or pins.
As the RX/TX connection to the FTDI chip on board is through 1k resistors, the signals will be overridden by the external device. Just connect it as I proposed in my posting. Make sure that RX/TX should be connected to RX/TX and not vice versa.
thankyou deSilva, I ordered the mentioned ftdi board a couple of days ago maybe a few more til it arrives but I will try wiring it as per your suggestion and I will post the result, once again many thanks for your help. I am just starting to get involved in electronics again after about
20 years of absense, so Iam a little rusty but I hope to stay involved
and Iam particularly interested in embedded systems and hope some day I can actually help, and be more of a contributor to this form.
