J-Link 10-pin Needle Adapter
The J-Link 10-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.
Why choose the J-Link 10-pin Needle Adapter:
- 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 J-Link 10-pin Needle Adapter comes with the option to power the target hardware via J-Link
These features make the J-Link 10-pin Needle Adapter the perfect solution for debugging and production purposes.
|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.

Preparing J-Link to supply power
In order to supply 5V power to the target, you may have to configure J-Link once as follows:
- Make sure that SEGGER J-Link software is installed on your machine. It can be downloaded from here
- Start J-Link Commander, which can be found under “Start -> Programs -> SEGGER -> J-Link ARM”
- Enter the following command: power on perm
- Plug in the adapter: The LED on the emulator side should now be lit
