U-Reach eUSB Converter 2.54mm (USB Dom to USB), 5-Pack

I had never heard of eUSB cards until a month ago. I figured there had to be some sort of adapter. When I searched Amazon I found this, got it, and it worked perfectly. Note that there are two standard connector pin spacings: 0.1 inch (which these are) and 2mm. Measure before you buy.

Excellent product, high quality build, made flashing of our usb DOMs a breeze
