T-Camera S3 power supply
I'm tinkering with a T-Camera S3.
I flashed it with ESP Home and everything works fine on USB power: the display, the camera, the PIR sensor, etc. It took sometime to nail it, but it worked out.
I have been trying for some days now to power it up via the JST-PH (5V or 3.3V) or JST-GH connectors. Unfortunately that yielded no results. The board does not power up.
Any ideas what I could try? Or how to go about figuring this out?
I am somewhat new to electronics, but I am very willing to read and learn.

For what it is worth...there has been an absolute RASH of users that now cannot run on battery. See the 'recent' history (clock face icon) of this community site.
I do not have one to test, but here is the schematic:
It shows three buttons, but I can only see two.
Many S3 models need a line in the sketch to power on the display when not on USB, or need to press a PWR-ON button.
BTW it is a very sophisticated board with a complicated power supply chip, so hard to troubleshoot from Canada!!!
@teastain2 hey Terry, thanks!
I noticed that people had this issue, but wasn't completely sure it applied to my situation as well.
I wonder if it has anything to do with the firmware... Or it's just a hardware thing?
@teastain2, just wanted to thank you. Your answer nudged me to search for another type of solution and I figured out a way to make it work with the USB-C.
Thanks a lot!
