Overview

The 6-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 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'' connector to a 6-pin needle connector.

Key features

No additional connector required on your PCB
Very small footprint - even smaller than the footprint of the 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
Please note: If JTAG support is required, use the 10-Pin Needle Adapter instead since the 6-Pin Needle Adapter does not provide enough pins for JTAG.

Pinout & schematics

A diagram showing a 6-pin needle connection with labeled pins: VTREF, SWCLK, SWDIO, SWO, and RESET. On the left, it is labeled "Probe / Programmer." The connection setup is represented within a rectangular outline.

The adapter features three locating pins for precise positioning and two support legs on each side of the connector for a stable and secure connection between the pins and the PCB.

The background is plain white, emphasizing the tools and connection. — In case of space problems, the two "legs" on each side can easily be cut off as shown in the image.

Footprint

To ensure reliable operation of the 6-Needle Adapter, we recommend implementing the footprint layout according to our specifications and following the PCB layout guidelines provided. This helps avoid common layout issues during the development process and ensures a stable connection to the flasher.

The complete footprint, including all technical specifications, dimensions, and additional information about the cable, plug, and connector, can be found in the PDF datasheet.
