<![CDATA[T-Camera S3 power supply]]>Hello 🙂

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.

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!

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?

See the 'recent' history (clock face icon) of this community site.
I do not have one to test, but here is the schematic:
https://github.com/Xinyuan-LilyGO/LilyGo-Cam-ESP32S3/tree/master/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!!!
