SWD (2x5 1.27mm) Cable Breakout Board
This Adafruit SWD adapter board helps you connect JTAG/SWD tools like JTAGulator, STLink or SEGGER J-Link to ARM boards using a 2×5 1.27mm (0.05") 10-pin SWD connector. No cables included — board and header only.
This Adafruit adapter board makes it much easier to program and debug ARM development boards that use the slimmer 2×5 SWD connector with 0.05" / 1.27mm pitch. It’s especially handy when working with tools like the JTAGulator, STLink, or SEGGER J-Link, and small boards that use the standard 10-pin SWD programming header, often found on Cortex-M0 and Cortex-M3 designs.
Please note: this board does not include any cables or a breadboard. It’s supplied as the adapter board itself, with header included if you need it, and is a useful add-on for anyone doing JTAG/SWD programming or debugging.
Specifications
- 14mm x 18mm x 7mm
- Weight: 1g
Revision History
- As of October 2022 – we've updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen - you may get the new PCB or the older version with vector fonts - both are identical other than the fancy silkscreen.
Resources
- EagleCAD files on GitHub
- Fritzing library
Package Contents
- 1x SWD (2x5 1.27mm) Cable Breakout Board
- 1x 9-pin header
