General • Power Pico without using on board usb connector

Hi,

Before I do something stupid and blow up my Pi Pico, I'm wondering if someone could confirm what I am going to do will work without creating magic smoke ?

I have a keyboard plugged into the Pi Pico onboard microusb connector using an OTG cable so I can use tinyUSB.
I have a micro USB breakout board I am using to connect a USB cable to my PC monitor for a 5v power source.
I have connected ground from the micro USB breakout board connector to pin 38 (GND) on the Pi Pico.
I have connected 5v from the micro USB breakout board connector to pin 40 (VBUS) on the Pi Pico - I read I should use VBUS not VSYS in Pi Pico datasheet states in section 4.5

If you are using Raspberry Pi Pico in USB Host mode (e.g. using one of the TinyUSB host examples) then you must
power Pico by providing 5V to the VBUS pin

Is this all I need to power the Pi PIco safely, I did read about using a diode but I think this is if you have 2 power sources....

Thanks

Steve
