I have been searching around to locate if anyone is making a board like this mainly for the Boron:
Admittedly, my google-fu is weak in locating items like this. For field deployments, the screw down terminals would be a boon, especially in harsher environments like we are attempting to deploy to. We could fashion our own but through I would ask.
@blacklensman another alternative is the MikroE Feather Adapter. Note that this can be used with any of the Feather format devices including the Boron. I would still power the device via the Boron USB, but I have used the board for some personal projects with good success!
