Pre-arm default

ArduCopter Copter 4.6
1

Hi from a newcomer in the ArduPilot world

During the COVID confinement I have built a quadricopter with an OpenPilot flight controler REVOLUTION full size. Then I moved to LibrePilot in the same direction. And then nothing when the developers stopped their interest for this FC.

So since a few weeks I have initiated a “revival” of my copter with your ArduCopter.

I have first tried and understand the differences. Then I have successfully loaded the firmware and begun the setup. The copter attitude is OK on my PC screen.

Today I have tested the GPS outside, OK. Then modified my motors list, OK.

But now I see a message “Pre-ARM Board (3,4V) out of range” which sounds like a REVO supply voltage of 3,3V instead of 5V expected form other boards. I did not find any menu or parameter to modify it and pass this error.

Any idea will be welcome.

Thank you to the team for your extensive work.

Regards

Jean

Hi

I had another look to the Full parameters list and I have found it. I have set BRD_VBUS_MIN to 3V, better fit for the REVOLUTION board and the default has desappeared.

Good opportunity to have a deep look to the parameters and better understand them.
