#2 Flash AI-Thinker ESP32-Cam example with Arduino IDE

In this post we will flash the ESP32-CAM module. If you did not setup your Arduino IDE for this module, have a look at this post here.

USB to TTL serial converter

As you can see this module have no USB input with serial converter. So we use an USB to TTL serial converter to flash the module.




Connect your ESP32-CAM module with an USB to TTL serial converter like the schematic below.

Schematic

ESP32-CAM              USB to TTL

U0T                  -->        RxD

U0R                  -->        TxD

5V                  -->        5V

GND                  -->        GND

Don't forget to connect IO0 and GND on ESP32 board (blue wire in schematic). If you forget it, it is  possible that you get an error by flashing.



Flashing
Make sure that power supply is stable. Often TTL converter power output is unstable. I recommend to use an external power supply.

1. Connect your ESP32 module with TTL converter to computer.

2. Press upload


If upload was successfully the following message appears in console.

3. Remove wire between IO0 and GND.

4. Open serial monitor

5. Press reset button

ESP32-CAM module try to connect to your network. Make sure your network has a stable signal. If wifi signal or power supply is unstable curious errors will appear.
After successfully connection to your network an IP address appears in  serial monitor.

6. Copy IP address to a web browser like google chrome and press enter.

ESP32-CAM server dashboard load in your web browser. Scroll down and press "Start stream" to start.
