in my project I have to power the Raspberry pi over the GPIO port. I know that the voltage must be regulated to 5V. My input is 24V so I have to convert it to 5V. I'm currently designing a PCB with the power regulation in it. So after research I find 2 chips to do this job: the LM2596 or the 78S05. But I don't know which one use.
My questions are the followings:
- Which chips is the best and why?
- If I power the Raspberry pi over the GPIO pin will be I always able to connect USB devices?
Thanks in advance!
