Professional Programming Cable for ARM Cortex Debugging
The Tag Connect TC2050-IDC-050-ALL-20 cable eliminates the need for expensive programming headers on your PCB whilst providing reliable JTAG and SWD debugging capabilities. This professional-grade cable connects directly to a minimal footprint on your target board, saving both cost and space on every PCB.
Direct PCB Connection - No Header Required
The spring-loaded pogo pins make secure contact with your PCB pads through precise alignment holes. The "with legs" design features retaining clips that lock the cable in place during debugging sessions, eliminating the need to hold the cable manually whilst setting breakpoints or stepping through code.
ULINK2 & ARM Cortex Compatibility
Designed specifically for ARM Keil ULINK2 debuggers and similar tools using the Samtec FTSH-110-01 style 20-pin 0.050" pitch micro-header. The cable connects pins 1-10 from the TC2050 footprint to pins 1-10 of the 20-pin connector, with pins 11-20 left unconnected as per standard ARM debugging protocols.

Wiring Quick-Start
PCB footprint requirements:
Connect the 20-pin IDC connector to your ULINK2 debugger with pin 1 aligned to the red stripe on the ribbon cable. The TC2050 end aligns with your PCB footprint using the three precision guide holes.
