Hi Albill,

Yes, thankfully most small screens can tolerate voltages in a range between 5 and 12v (although this is seldom advertised). 5V is really the lower end, and some screens won’t tolerate such a low voltage. To make up for the lower voltage, it draws more current and so this must be kept in mind. On another project, I first tried powering a screen through the raspberry pi’s GPIO pins but this output wasn’t high enough and so it kept cutting out. I then just split the powerfeed to the raspberry pi and it worked fine.

Regards

Mat
