Adding back-to-back 2.54mm screw terminals to the Portenta Breakout Board
I discovered a little trick. You can extend and straighten the pins in the 2.54mm spaced pins of a screw terminal block. Then you can put them back to back. Use needlenose pliers to straighten them. A little vice can help a tiny bit getting things started. Put them in in groups, and twist them down a tiny bit with the pliers (Orange circle is before, Purple circle is after):
