This adapter board is designed for adapting a 'classic' 2x10 (0.1"/2.54mm pitch) JTAG cable to a slimmer 2x5 (0.05"/1.27mm pitch) SWD Cable. It's helpful for using products like the JTAGulator or SEGGER J-Link with tiny boards that use the 10-pin SWD programming connector.
This board comes with no cables. It's really just the adapter - but is super helpful when you want to use JTAG debugging on boards that can't support 2x10 cables. We do stock the SWD cable if you need one here!
Jargon buster
Plain-language definitions for the technical terms used above.
- JTAG
- JTAG is a hardware debugging and programming interface used to inspect and control chips at a low level. It matters for advanced development because it can help diagnose firmware problems that are hard to see through normal serial output.
- SWD
- Serial Wire Debug (SWD) is a two-wire programming and debugging interface used with many ARM Cortex-M microcontrollers. It provides low-level access to program, recover or debug the microcontroller.
