RRF vs PanelDue compatibility?

Is there anything else I should / could try to make sure it's not the duet2 board first?

Not that I can think of that hasn't already been tried. Unless @dc42 has any other suggestions.

If the voltage at the PanelDue power input pins on the 4-way connector is a steady 4.98V even when the display is flashing white then the fault lies in the PanelDue.

My guess is a badly-soldered diode DA2 or inductor LA1 (or just possibly LA1 is the wrong component). If you wish, you could check that by measuring the voltage between each end of LA1 and ground. Both places should be steady at about 4.5V.

@dc42 Before I do anything stupid...(I'm a mechanical engineer not a sparky), which side of those components should I check on?

I'd assume the side opposite of the 4 wire connector, is that correct?

As you are not sure, I suggest you just ask for a warranty exchange.

@dc42 FYI the new PanelDue got here today, I plugged it in and it worked, so good call there. Thanks.
