Trying to make multi adapter - it fits Tang Primer, and Tang Nano FPGAs. Not tried it in anger yet, does pass continuity tests with multimeter. Am suspecting RF issues at high frequency.

Going to try this shield paint on the part as an experiment, once the weather is clement, as it cannot be used in the house because fumes.
I will sit an SDR next to it for a before/after looking for changes in emmited noise, when running a HDMI source pattern from one the tang devices.
