J-Link 6-pin Needle Adapter

The J-Link 6-pin Needle Adapter has been designed to connect J-Link to a PCB which does not come with a mating connector or programming header. The designed pattern with 3 locating pins ensures, that the adapter can only be connected in one way.
The 6-pin Needle Adapter allows manufacturers to save costs and space on their PCBs since there is no need to provide the PCB with additional connectors.
It adapts from the standard 20-pin 0.1'' J-Link connector to a 6-pin needle connector.

J-Link 6-pin Needle Adapter is compatible with J-Link BASE, J-Link PLUS, J-Link PRO, J-Link ULTRA+, J-Link EDU, Flasher ARM, Flasher RX, Flasher PPC and Flasher Portable.

Note: If JTAG support is required, use the J-Link 10-pin Needle Adapter instead, since the 6-pin Needle Adapter does not provide enough pins for JTAG.

Why to choose the J-Link 6-pin Needle Adapter:

  • No additional connector required on your PCB
  • Very small footprint - even smaller than the footprint of the J-Link 10-pin Needle Adapter.
  • High reliability spring pins for secure connections
  • Designed with 3 locating pins, so the adapter can not be connected the wrong way

These features make the J-Link 6-pin Needle Adapter the perfect solution for debugging and production purposes.



Pinout

As you can see on the image below, the three locating pins ensure, that the adapter can not be connected to the PCB the wrong way. Moreover, the two "legs" on each side of the connector guarantee a stable and secure contact between pins and the PCB.
