TC2050-ARM2010 ARM 20-pin to TC2050 Adapter ARM 20-pin to ARM 10-pin JTAG or ARM SWD using TC2050 Cables Plug-of-Nails Cables. (Pictures for illustrational use only - TC2050-IDC Cable and Seggers J-Link Debugger not included ) Tag-Connect - Save Cost and Space on Every Board The TC2050-ARM2010 is a Tag-Connect adapter board allowing our TC2050-IDC cables to be used for ARM JTAG and ARM SWD (Serial Wire Debug) applications. Although intended for use with our patented TC2050-IDC Plug-of- Nails Cables, the adapter may be useful to people wishing to use 10-pin 0.1 ribbon headers on their PCB.

Solder bridge two pads as shown or select GND to improve signal integrity if power is not required. Note that some debuggers (ST-LINK/V2 for example) supply +3.3V instead of +5V. ** Pin 9 of the 10-pin connector (pin 9 of the TC2050 footprint) can optionally supply nTRST - solder bridge as shown.
