J-Link 2mm Adapter

The J-Link 2mm Adapter adapts from the standard 20-pin J-Link connector to a 20-pin 2mm-pitch connector. The J-Link 2mm Adapter is a 1:1 adapter, since the pinout of the 2mm pitch connector is identical to the standard 20-pin J-Link connector.

Pins 14, 16, 18, 20:
On some models like the high-end model J-Link PRO,  these pins may not be connected to GND but are reserved for future use/extension. In case of doubt, leave open on target hardware.
