SEGGER 10-Pin Needle Adapter for J-Link Debug Programming

Product Code: 8.06.04

Advanced Needle Adapter for Connector-Free Programming The SEGGER 10-Pin Needle Adapter transforms how engineers connect J-Link and Flasher debug probes to target PCBs. This precision adapter eliminates the need for mounted connectors on your circuit boards whilst providing reliable spring-pin contact to a specialised footprint pattern. Foolproof Connection Design Three strategically positioned locating pins ensure the adapter can only connect in the correct orientation, preventing costly connection errors during development and production programming. Cost-Saving PCB Design: Remove headers, save board real estate, reduce BOM costs by up to 15p per unit whilst maintaining professional debugging capabilities. Technical Specifications Input Connector 20-pin 0.1" (2.54mm) standard JTAG/SWD Output Pattern 10-pin 0.05" (1.27mm) needle pattern Spring Pins High-reliability, >100,000 cycle rating PCB Footprint Minimal space requirement with tri-pin keying Target Power Optional 5V supply via pin 9 (300mA max) Signal Mapping & Pinout The adapter provides full JTAG and SWD signal access including: JTAG Signals: TCK, TDI, TDO, TMS, TRST SWD Signals: SWCLK, SWDIO, SWO Control: RESET, VTref, GND Power: 5V target supply (optional) Needle adapter PCB footprint pattern with positioning guides PCB Layout Requirements Pad Specifications: - Contact pads: 0.8mm diameter minimum - Positioning holes: 0.7mm diameter - Solder mask: Must be clear of contact pads - No solder paste on needle contact areas - 0.5mm clearance from other traces Compatible Debug Probes Works seamlessly with all SEGGER debug tools including J-Link BASE, PLUS, PRO, ULTRA+, EDU, and Flasher series.

The 20-pin standard interface ensures universal compatibility across the SEGGER ecosystem. Production Programming: Ideal for high-volume manufacturing where repeated connection cycles demand reliable contact without wear on target PCBs.
