There are other ESP32 based camera modules available that should work if the pins are set in the sketch. Ttl Serial Camera Arduino Update To TheIf you prefer to work with your ESP32 in the Espressif IDF theres another guide here: ESP32 Camera Module with Face Recognition Adding or Updating the ESP32 Range in the Arduino IDE If youve never used an ESP32 board in the Arduino IDE you need to follow the first part of this tutorial: ESP32 Built-in OLED Heltec WiFi Kit 32 If you already have the ESP32 boards available in your IDE then you just need to update to the latest version of the board libraries. To do this, open the Arduino IDE and in the menu: Tools Board:xxxxx Boards Manager: Search for ESP32: Update this to the 1.0.4 version. Face detection is broken in versions 1.0.2 and 1.0.3. Connections The ESP32-CAM doesnt come with a USB connector so you need either a CP2102 or a FT232RL USB to TTL Serial Converter to connect it to your PC. When using WiFi the ESP32 can use more current than is supplied via USB through these devices resulting in the module crashing and rebooting. I found the top device worked fine (I bought it here ) but the FT232RL didnt work for me. If you use a FT232 with 5v and 3.3v, set the voltage jumper to 3.3v. You might be able to use the 5V from the side of the board to power the 5v pin on the camera. USB to Serial TTL Above FT232RL Below Wire the module according to the diagram above. The green connection should be connected when flashing the module and disconnected when running. Running the Camera Web Server Example Plug in your module and change the board settings to these: Open the Sketch by navigating File Examples ESP32 Camera CameraWebServer: Edit the Sketch defines to look like this (assuming you are using the Ai-Thinker module): Select camera model. Check that the IO0 pin (green in the diagram) is connected to GND and press the reset button under the module and try again. Press the reset button on the ESP32-CAM and watch the start up sequence in the serial monitor: Look for the IP address that the ESP32 has been given on your network. ![]() ![]() You can see the two different settings below: If you have a low frame rate or poor reception this might well be the problem. You can either move the jumper with a bit of very careful soldering or buy an IPEX WiFi antenna which will improve the signal.

Keep posting, Im interested in your adventures with the MAIX board. Reply WordBot says: January 18, 2019 at 2:30 pm Thats great thanks The MAIX is very interesting but they have a way to go to get to where the Espressif boards are with libraries etc. From the same TTL adapter i use 5V and GND and connect it to 5V and GND on the ESP32 cam board. Not sure is it ok. Any idea Reply WordBot says: January 22, 2019 at 3:26 pm I found that with the FT232RL connected with a USB cable that when the wifi started up it would crash with the brown out error. The other connector I plugged straight into my PC (no cable) and this was fine. It could be your adaptor or the USB cable that cant carry the current needed.
