mbed power dip when plugging in USB Cable

20 Apr 2011

Hi All,

I have a small problem that I'm just getting around to... When my mbed is running on it's own seperate power supply and I go to plug in the USB cable for my computer, the mbed has a dip in power and it "reboots"...

Is there any way to stop this?

Do you have anything connected to the 5V output (pin 'VU')

I have experienced the same thing. I have nothing plugged into the 5V output

That works fine for me. I have a power supply (8.4V) with a 5V voltage regulator supplying the mBed, and it works fine plugging in the USB cable when running on another power source.
