J-Link 19-pin Cortex-M Adapter

The J-Link 19-pin Cortex-M Adapter allows JTAG, SWD and SWO connections between J-Link and Cortex-M based target hardware systems.

It adapts from the 20-pin 0.1'' JTAG connector to a 19-pin 0.05'' Samtec FTSH connector as defined by ARM.

The J-Link 19-pin Cortex-M Adapter may also be used to connect J-Link to a non Cortex-M target as far as the target connector uses the

same pinout as shown below.

By default, TRST is not connected, but the Cortex-M Adapter comes with a solder bridge (NR1) which allows TRST to be connected to pin 9

of the Cortex-M adapter.
