QQ2440V3 12 volt power - min/max amps required and FUSES.

[darthracing]

Hi,

I am using a DC/DC converter to power my board on my vehicle, but I need to aquire a new AC/DC converter to run the board.

The AC/DC converter shipped with my board had a bad connector wire and so I never used it. It says 12V-2.5A which would be ~25W, I assume thats much higher than necessary or even allowed.

I would like to go as small as possible on the AMPs, and avoid putting too much through the board
(I am running USB Hub w/USB Bluetooth, WIFI, the RS232 port and SDCard) what is the appropriate MAX amperage to allow
to run through the board?

Thank you,
Todd

This should be simple, wire up your multimeter to measure the current of your current setup.
See how much it needs, then youll know 100%.
