Hi, I'm mounting a Due in a project box and won't really have access to the programming jack. I was wondering if I can add another one?
Is there a diagram that shows which line is hooked up to each pin on the micro USB programming jack?
I'm thinking I only need to connect to TX0, RX0 and GND, is that right? Would I need resistors or is direct connection ok? The Due will be powered via other means.
But I have no idea which pin Tx0 should go to etc...
USB data is sent on a high speed balanced differential pair, so layout considerations are important - can
you not plug an extension lead into the port?
Two years ago, piqued by curiosity, I was able to program flawlessly a genuine Arduino Due using the Taijiuino Due programmer connected to the pins TX0, RX0.
Here a link of the programmer:

Is it not the same as the USB Serial Light Adapter ?

Is similar to it (I didn't check the specs/schematic). Both adapters could be a cheap/quick solution for a stuck-Arduino ostrich.

Ok thanks, I'll just try and deal with it. I was hoping I could just move the port to another board, oh well.
