I just received the reTerminal with rPi, the device makes a very audible high pitched noise when powered on.

This seems to happen no matter which power supply im using.

Hello.
What sizes of power adapters have you tried?
It is also possible that there is a problem with the capacitors.

#3

I’ve used a 65w power adapter, and a 15w power adapter - both USB-C

I’ve also used a USB-C cable from my laptop to power it, all 3 result in the same issue.
