Crius V2 current help!

[Commando]

Hi!
A just want to know what is more efficient for my electrics.
I have:
Extend board GPS (xbee ready)
Receiver
Bluetooth
3DR telemetry
Minimosd

For sure if I plug all them together, the 5-5.3V that crius want will not be enough.
So I make some mesurments I plug UBEC 5V/5A to crius. The UBEC shows 6V. I measure the voltage that crius provides to GPS/Bluetooth, and shows 5.5V.
I';m thinking to connect GPS/BT/3DR/OSD/receiver to another UBEC for giving crius the right voltage.

My questions are: what is my amperage consumption?
Is crius OK with UBEC 5V/3A? So the all others connect with UBEC 5V/5A?
Is it OK if I connect all together with one UBEC 5V/5A;
Why UBEC 5V or 6V actually are 1 volt higher? (6V or 7V)
If I solder the diode it will give 6 volts. Isn';t that dangerous?

• Probably about 100ma in total
• Overkill
• Yes
• Usually because it has no load on it.
• The diode could create a bottleneck and limit the current

Thanks appreciate!!!
What your suggestion for the diode?

I can connect all with a UBEC hobbiwing 5V/3A 5A max.
and provide them all with crius power?

It has the option 6V. Should switch to 6V?

Or should I use CRIUS UBEC 5V/5A?

[pheasant_plucker]

6v will be fine as the Crius has it';s own voltage regulator built in.
I don';t know what diode your referring to! If it';s on the Crius then it could be for polarity protection and I would leave it as is.

Results:
All plugged
Powered from crius board: extend board (GPS), 3DR telemetry, bluetooth
From UBEC: minmosd
Hobbywind  UBEC 5V 3A (5V selectd) from 6V (actual) = 4,90V
Crius UBEC 5V/5A = 4,80V
Messurment did from digital port power pin

Are 4,90V OK for atmega?
Change the jumper from hobbywing it will goes (6V) actually 7V and drops to 5.90V
Suggestions?
Cheers

I';m running GPS and Minim OSD directly form the CriusAIO controler and I don';t have any problems. I';m powering the Crius board directly from a 3S battery. If you want you can power your peripherals from an external Ubec and not worry about the Crius power regulators no?

Thanks for your reply,
I decide to plug all to the board. Everything looking good!
