Allo USBridge board

[dabassgoesboomboom]

It seems odd it works with just one.

As I mentioned a few posts above, it’s actually recommended, so not odd that it works at all…

I also mentioned the reason it works this way is because there is a diode that allows this, which was explained in this thread before:

Allo USBridge board

Only Ethernet Connector body is connected to GND. Aluminium case not connected to GND. J28 opens state - Feeding power from Sparky to USBridge is blocked by reverse diode. In this mode power can feed to USBridge alone or we can feed 2 power source separately. On Allo web GUI enable roon only.
