These little cables are handy when programming or debugging a tiny board that uses 10-pin 1.27mm (0.05") pitch SWD programming connectors. We see these connectors often on ARM Cortex dev kits, and a spare in the ARM-dev box is useful.
One cable per order. The ribbon cable is 0.06mm/0.025" pitch and the connector is a 1.27mm (0.05") pitch 2x5 box. These are not for use with programming most AVRs or other large devices that have 0.1" pitch connectors so be aware which you need!
