Ubuntu 22.04

Please describe your issue below:

I would like to use the 40-pin header on the VIM 3/4 board to connect external devices.

To do this, I would like to know the maximum voltage that the 5V and 3.3V power supply pins on the 40-pin header can output.

It is also important to know whether this depends on the load on the board itself or if it is completely independent.

• 5V/500mA
• 3.3V/1A

Avoid attaching excessively high-load peripherals, as this may compromise the motherboard’s integrity or lead to hardware failure.

Does that mean each 5V and 3.3V pin can output these voltages individually?
