It's an ESP32 board with a camera, running a web server, so it acts as an inexpensive webcam.


To install the camera:

  • flip the black part of the camera connector 90 degrees so it points up
  • place the camera connector, contacts towards the PCB, camera facing up
  • gently slide the connector in place (about 2 or 3 mm of travel), e.g. pushing with the screw driver onto the rigid part of the camera connector towards the white part of the PCB connector
  • flip the black part of the connector back into the flat position.

Pins (ESP32 cam to USB serial converter):

  • ESP-32 5V to USB serial 5V
  • ESP-32 GND to USB serial GND
  • ESP-32 UAR to USB-serial TX
  • ESP-32 UAT to USB-serial RX
  • ESP-32 IO0 looped to ESP-32 GND (they are next to each other), you can use a jumper or a dupont wire. CLOSED for flashing, OPEN for running.



The CameraWebServer example can be compiled as a platformio project:

To build the code, clone the git repo above, cd into it, then type

 pio run

To upload it to the board (put a jumper between IO0 and GND):

 pio run -t upload

To watch the debug output (remove the jumper):

 pio device monitor

Platformio can be installed on a Debian Linux system as follows:

 sudo apt install python-pip
 sudo pip install platformio
 pio upgrade
