I agree, the USB connnector on the Photon is very fragile. Pull a bit too much on it and you will end up with an unreliable connection later.
The displays are also a bit fragile and up for change in a new version. Should we try swapping it? If you send me your address I’ll ship you one.
Or would you prefer to send the entire BrewPi back so I can investigate? Perhaps without the enclosure, so it can fit in a flat mail envelope.
