ESP32 CAM not turning on through USB TO TTL

[agtechie]

I was working on a project where i needed to power an esp32 cam through the usb to ttl programmer but that doesn't seem to power on

I've used the programmer multiple times before to upload the code to the esp32 but it doesn't work. I do use it to upload code to the esp8266 and that works.

All 3 esp32s that i tested with their hub work but not when I use them with the usb to ttl.

I don't know much about esp32 cam so any help would be appreciated

PS. The USB to TTL programmer works fine as I've tested it multiple times with multiple devices before

doesn't seem to work

You might get more help if you explain what 'doesn't seem to work' means.

Hi! Welcome to The Forum.

Definitely a good question.

Another one is: how are you connecting the programmer to the ESP CAM?

Recently I used the ESP32-CAM. I had to connect the USB to TTL to the camera with 4 jumper wires. Then I had to connect the ESP32-CAM to the computer with a USB cable.

Well I used the standard connections for the esp32 cam and the usb to ttl module

I don't know how but it suddenly started working. Currently its connected to 5V-5V and GND-GND. The other VIN and 3v3 pins on the ESP still aren't working, as in when I connect those to the usb they dont power the board, but the 5v pin works fine, except for one thing:

The boards seem to be heating too much, something I have seldom observed while working on it a few months ago, but its happening everytime i connect it to my macbook now.

Yes I did the same and it works now, except that I'm having a overheating problem.
Thanks for responding though

You don't use the 3.3V, just the TX, RX, 5V, G. OR use a normal USB cable.

This might be the connection, with special attention to IO0 - GND while uploading a sketch:
