The J-Link Mictor 38 Adapter connects the standard 20-pin 0.1" J-Link interface to the 38-pin Mictor interface. The pinout follows the single target connector pinout specification as defined in the ARM "ETM Architecture Specification".

The adapter connects the GND and JTAG pins to their counterparts on the 20-pin J-Link. Trace pins present on the Mictor connector are not connected as they are not present on the 20-pin J-Link connector. The 38-pin Mictor side of the adapter can be plugged either directly into the target side or via trace cable. The J-Link side connects to J-Link via 20-pin flat cable.

If you need trace capability, take a look at the J-Trace Debug + Trace Probe.
