The 10-Pin Needle Adapter has been designed to connect J-Link or Flasher 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 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'' connector to a 10-pin needle connector.
- No additional connector required on your PCB
- Very small footprint
- High reliability spring pins for secure connections
- Designed with 3 locating pins, so the adapter cannot be connected the wrong way
- No external power supply required! The 10-Pin Needle Adapter comes with the option to power the target hardware via J-Link or Flasher
As you can see on the image below, the three locating pins ensure that the adapter cannot 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.

In case of space problems, the two "legs" on each side can easily be cut off as shown in the image below:
Please be sure to avoid the situations illustrated below to ensure the 10-Pin Needle Adapter functions properly. The PDF version of the datasheet can be downloaded here. In addition to the footprint and hints to avoid layout problems, this PDF includes detailed information about the cable, plug, and connector of the 10-Pin Needle Adapter.
