USB-JTAG module schematics for VC707

I am trying to repair a microUSB connector which is out of its place from VC707. Could anyone advise if the attached Molex connector part that I have will fit in okay into the original connector location ?


Below is a camera screenshot on the board location where the USB connector is supposed to locate before it is out of its place. I could not find any reference number near that connector.

It seems like the full schematics and its connector part list of U26 USB-JTAG module alone are not given in VC707 product webpage.

U26 is just the overall USB-JTAG module.
From what I have searched, it is neither J2 nor J17.

Your image links are broken.


Easiest option is probably to email Digilent (who make the JTAG module) and ask. While they do guard the schematic and the custom EEPROM contents for their USB-JTAG adaptors carefully, I doubt that they'll mind you replacing the USB connector. You could also ask if they'll just sell you a JTAG-SMT1 (an exact replacement for that module), although they probably don't have any more stock.


With that said, in my experience, there are basically two things to watch out for with micro USB connectors: mounting orientation and through-hole pins. They're available in both normal and inverted orientations, and they'll have either zero, two, or four through-hole legs for mechanical stability. As long as you match those, most brands will fit the same footprint.
