Need help to setup ESP32 CAM and get it to work

I need help setting up my esp32 camera

when I tried to upload a LED blinking code, I received this error message:

I followed the connection as shown and I am using FTDI1232

ziyor · July 15, 2024, 9:05am

This is the output when i press the reset on the ESP32 CAM

J-M-L · July 15, 2024, 9:07am

does it support 3.3V for the Tx Pin ?

ziyor · July 15, 2024, 9:08am

it operates either at 3.3v or 5v

J-M-L · July 15, 2024, 9:11am

did you set it up at 3.3V (that's what the ESP32 pin expects)

ziyor · July 15, 2024, 9:13am

yep I connected it accordingly but I keep receiving error messages

J-M-L · July 15, 2024, 9:18am

are you sure you connected GPIO-0 to GND ?

can you try to reset the module at the moment when the IDE tries to upload the code?

ziyor · July 15, 2024, 9:24am

This is my setup

second pic the white cable from the FTDI is connected to U0T

typical set-up

your module seem to have a jumper to select 3.3V so that's fine where you have it

with your module it would be

did you try resetting the ESP32 at the moment of upload ?

ziyor · July 15, 2024, 9:43am

yes

ziyor · July 15, 2024, 9:46am

I tried connecting 3.3V Vcc cable to the place shown in your picture
I got this error

seems you are powering on the 3.3V pin - connect to the 5V pin.

(if you have a DMM double check the voltage out of your FTDI module, it might be 5V not 3.3V. The jumper might only be for the Tx and Rx / logic )

ziyor · July 15, 2024, 9:51am

I have checked alr. the voltage appears to be correct. I have tried connecting the 3.3 pin on the FTDI to the 3.3v pin on the esp32 cam and the 5V to 5V i still cant seem to get it to work

srnet · July 15, 2024, 11:20am

With ESP32CAMs take care with which GND pins you use for the connections.

On some more recent ESP32CAMs the 'GND' pin next to UOT is an ENABLE\RESET pin, it might be labeled GND/R too.

ziyor · July 16, 2024, 1:33am

Its the AI thinker model. I don't think there is a enable/reset pin, also I tried both of the gnd pins

J-M-L · July 16, 2024, 9:22am

it seems you are doing the right steps
did you check the Dupont wires for continuity? some cheap ones have a tendency to break inside.
