Skip to product information
This SWD cable connects your debugger to ARM Cortex processors using the standard 2x5 pin connector format. It's the straightforward way to establish a Serial Wire Debug connection without hunting around for the right pinout. The cable terminates on both ends with 2x5 pin headers, so you can plug it directly into your development board's SWD port or your programmer's output.
The connector follows the standard ARM SWD pinout, which means it works with most modern microcontroller development boards and in-circuit debuggers. Whether you're programming STM32 chips, nRF series modules, or other ARM-based devices, this cable handles the connection cleanly. The robust construction means it won't wiggle loose mid-flash, which is helpful when you're trying to debug something at 3AM.
This is one of those utility cables you'll reach for constantly once you start working with ARM development. It's industrial standard, uncomplicated, and does exactly what you need it to do. No special software required, no configuration headaches—just plug it in and start debugging. Keep one in your toolbox if you work with multiple ARM platforms.
