Hi. I could not find any good advice on this here, so sorry if there is a thread with this already...
I have a project with quite a lot of displays, LEDs and external ICs, so I'm going to need to supply the 3.3V rail with an external regulator. This is not a problem and is currently working, I did cut the trace to seperate VIN from VUSB. Now I wanted to use the USB Host, which obviously needs 5V to operate. How do I provide 5V to the Host Port? I really would like to have the protection of the TPD3S014 chip provided on the board, so can I just provide 5V with another regulator on VIN? Or is it better to just supply the VHOST directly?
Thanks in advance for any help and advice!
