Thanks
Depends what you want to connect it to, what's on the other end?
Most of the debugger manufacturers sell them to go with their product (for a hefty fee).
I believe the connector is a Samtec FLE-105-01, but that doesn't help you very much unless you want to build something yourself.
The connector is Samtec FTSH-105 series. You can buy the connector from Samtec, Digikey or mouser. The ribbon cable for that can be found here, select the 10 pins, 1.27mm pitch.
Isn't the FTSH the male/pin side not the female/socket side?
Yes, I meant the connector that is on the board. On the cable side any 1.27 pitch female would do no need to be Samtec. Link I provided is for the ready made cable.
