Obviously, my assumptions are wrong 😊
It looks to be a normal dev kit with 2 usb connectors and no usb hub.
I could not find the schematic for this specific board but looking at the pictures I would expect it follows standard ESP32-S3-DevKitC-1 (https://docs.espressif.com/projects/esp-dev-kits/en ...

Not sure which dev kit type ESP32-S3-WROOM is.
It might be the one from Waveshare (https://www.waveshare.com/wiki/ESP32-S3-DEV-KIT-N8R8) which has a single USB type C connector and a USB hub in between. The hub has 2 downstream ports connected to ESP32-S3 USB port and to USB2serial chip

If it works when connected po a pc but not when is direct powered by 5V, then the cause might be the 2 transistors used to generate reset and boot signals by the usb to serial converter. Not sure if your board has them but it worth to check the state of reset pin. if low when powered by 5V, but ...

Hello, can you post a picture/ ckt diagram of your connection?

The ESP is connected to an MPU9250 accelerometer, a barometer, and five servos. The servos are powered by 6V. The power supply is a simple 2s lipo connected to a 5V regulator or step-down switch for these servos.

Hi, I'm having trouble powering my ESP32 S3 CAM ESP32-S3 by applying 5V to the 5V pin. The ESP doesn't respond, the "ON" LED doesn't light up, and there's no voltage on the 3.3V pin. However, when I connect the ESP to my computer via USB cable, everything works fine. The problem is the power supply ...
