This compact adapter board makes it easier to work with ARM development boards that use the slimmer 2x5 SWD programming connector. It is designed for 0.05 inch / 1.27mm pitch SWD cables, commonly found on small Cortex M0 and Cortex M3 boards.
It is useful when connecting JTAG/SWD debugging tools such as JTAGulator, STLink or SEGGER J-Link to tiny boards with the 10-pin SWD connector.
The board is supplied as a breakout board with header if you need it. No cables are included, so pair it with a suitable 10-pin 2x5 1.27mm SWD cable for your setup.
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- 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.
