In this article, I am going to describe how to program ESP32 cam module using arduino IDE & without FDTI & any other USB to ttl converter.
This low price development board has onboard 5volt to 3.3-volt voltage regulator chip, an ESP32 chip with Bluetooth(BLE), wifi, GPIO pins, 2MP camera & a big sized SMD led but unfortunately this cheap board has not any onboard programmer chip like other nodemcu board. Usually, we have to program it using FDTI or USB to TTL converter.
IF you don’t have any USB to TTL converter & have an Arduino UNO then no need to waste money to buy this TTL converter.
You need to program in this method
- ESP32 cam ( I am using AI thinker)
- Arduino UNO board
- Jumper wire
- Arduino IDE software
Connection ESP32 cam to Arduino UNO
- Connect Arduino 5volt to esp 32 cam 5 volt.
- Arduino GND to GND
- Arduino RX to Cam board RX & TX to TX
- Arduino reset pin to GND
- ESP 32cam D0 to Gnd
Make sure the cam board DO is connected to gnd. It will enable esp 32 flash mode otherwise you can’t program it. after compleat, the programming remove D0 to gnd
Now open Arduino IDE on your PC, go to File > Preferences >
Now paste below link in the board manager URL
https://dl.espressif.com/dl/package_esp32_index.json
Now go to Tools > Board > Board manager > & search for ESP 32
You can see esp 32 board Download & install the latest version package
After complete, the installation go to Tools > Select port where arduino UNO is connected
- Now go to board > select board > ESP32 ” Wrover Module”
- Flash Mode > QIO
- Flash Frequency > 40MHZ
- Partition Scheme > Huge App (3mb No OTA)
- Upload speed > 115200
- Programmer > AVR ISP
Now it is ready for uploading sketch
You can test it Go to File > Example > ESP32 > Camera > Camera web server and upload the sample sketch
hey bro, i had tried to build program in esp32 cam module as pr ur instruction but it not success.
there are some error shown in ide
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
can u help me to solve this issue.
Hello Rucha,
make sure D 0 is connected to gnd
power connected to Arduino 5V & check all jumper wires
press reset on esp32 cam when uploading.
Esp32 wrover module board has not showing programmer option….how can I solve this
This is the solution that solved my “Timeout waiting for header” issue. I tried around 20 other solutions prior to this.
thanks
wow,thank u sir,Found best tutorial on internet…..
Thank You

I was able to find good information from your articles.
I think the admin of this website is genuinely working hard in support of his web site,
because here every stuff is quality based data.
Hi , is it possible to use RFID mfrc522 as well esp32 cam to function in one Arduino uno wifi board ?
yes… it is possible
I just wanted to give you a quick heads up!Aside from that, excellent website!
Excellent post. Keep writing such kind of inforation on yourpage. Im really impressed by your blog.
Hello there, just became aware of your blog through Google, and found that it is truly informative.I am going to watch out for brussels.
Exploring in Yahoo I ultimately stumbled upon this website.Studying this info So i’m glad to show that I have an incredibly excellent uncanny feelingI came upon just what I needed.
I’m really enjoying the design and layout of your blog.It’s a very easy on the eyes which makes it much more pleasant for me to come here and visit more often.
Very good article! We will be linking to this great post on our site.Keep up the good writing.
How do you actually use it?
you can make IOT & camera-related different project using it
bro in mine the programmer is not coming/showing.
Hello
I have problem can every body help me please
That I connected my arduino uno to the esp32 and uploaded the code from arduino ide to the arduino and it uploaded but when I opened the serial monitor that not appeared the IP address as above that write error
Camera_probe(): detected camera not supported
esp_camera_init(): camera probe failed with error 0×20004
So,can any one help me please …
A tu trouvé une réponse car j’ai le même problème.
Same issue. Have you got it solved?
meme probleme aussi
Any reason why it should not work equally good with the MKR1010 board (my UNO is occupied in another project)?
As soon as I connect the MKR1010 reset to GND, the USB port connected to are gone in the “Tools/Port”-list.
any thoughts on that?
Great tutorial btw!
hi Cudos to you ,I spent many hours trying to get my esp32 camera working . I tried many other videos which purported to do this but nothing worked. Your clear instructions worked first try and saved me from bying a new camera.
Thankyou so much
Greg Otto
Thanks buddy, Your article was very precise. I had many unsuccessful attempt to get my ESP32 cam up and working using the serial programmer. I stumbled upon your article of using arduino to program te ESP. it solved my 2 days of vain.
How can i get the menu to change the camera setting in the broswer. I seem to miss that in the current solution. Am I missing something pls suggest.
Thanks
Thanks again for the article post. Want more.
Good post. I learn something totally new and challenging on sites I stumbleupon every day.
It’s always interesting to read through content from other authors and practice something from their websites.
Hello,
Thanks for your blog it’s very informative.
I have an issue unfortunately after following all the mentioned steps, I can’t use any programmer in arduino IDE when I select different boards…any advice, please?
Thanks, You need to install esp32 board support package
Your way of explaining all in this article is really fastidious, every one can easily be aware of it, Thanksa lot.
my programmer is not showing when i select esp waver model…..please reply it is very urgent
I’ve been trying for days to get this working, but no luck. I’ve tried connecting via an FTDI interface board, no luck. I’ve tried connecting via an Arduino Uno, no luck. With the Uno I WAS finally able to get it starting to work, but it failed (again, as always) while uploading the Sketch with the error message “A fatal error occurred: Timed out waiting for packet header”.
It got PART of the way, with this info being displayed as it connected and started to communicate:

Both the TX and RX LEDs on the Arduino blink nicely, seeming to indicate that info is going to the ESP32-CAM and getting info back from it. But then it fails with that same error each time.
Everything is connected correctly. So why is it failing?
I will much appreciate any suggestions you can make.
Pls. check RX TX wires wires. press reset Button onece when uploading the code

Is there anything else I can do?
have you reset the esp32 before charging. and put the jumper on esp32?
Hello there, just became aware of your blog through Google, and found that it is truly informative. I am gonna watch out for brussels. I will be grateful if you continue this in future. A lot of people will be benefited from your writing. Cheers!
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
what to do now?
Same here.
Thank you, I spent days figuring out why my esp32cam was not working. I tried different cables and settings. My ftdi adaptor was defective and I have and Arduino fortunately
Does it work with the ESP32 NodeMCU also?
Thanks for sharing your thoughts. I really appreciate your efforts and
I am waiting for your further write ups thanks once again.

bookmarked!!, I love your site!
I attempted to follow your instructions, but for the programmer, it says no programmer available for this board.
