SWD UXplor

Debugging embedded code is so much easier with a HW debugging probe like the J-Link or Atmel ICE. But connecting these to Feather format development boards that don’t have a debugging header means adapting the board by soldering leads to you Feather.

We use Feathers from Adafruit and SparkFun all the time, in fact most of LooUQ's embedded development for the SAMD processors is done on one of these boards. Initially the SWD UXplor was designed for LooUQ’s in-house use to make embedded code debugging for our applications easier. Instead of using a collection of modified Feather boards in our lab, we can grab any one of them, put it in the project, and start debugging.

The SWD UXplor strikes a balance between being as small as possible and making the 10-pin debugging header accessible. The board extends only 7mm beyond the end of your Feather development board from the end opposite the micro-USB connector. For an Adafruit Feather your footprint is 58mm long; the total length of the Thing Plus with the SWD UXplor is 66mm long (the Thing Plus extends on the USB end beyond Adafruit units + the 7mm for the UXplor adapter).
