[Elphel-support] Is PSU board required when using PoE

[Richard Rigby]

Hi Andrey,

Thank you very much for your reply.

We will design some additional heatsink into our housing.

I think that we will end up ordering an extra power board otherwise I may
end up wiring up the 3.3 volts directly.

Kind regards,
