The ESP32-CAM module connects to Wi-Fi and falls into deep sleep The scenario I would like to implement is as follows: In our demo we will use the PIR motion sensor module that will occupy gpio13. Luckily, this will suffice for our needs. Since the ESR32-CAM board features a microSD card slot, we only have two free gpio’s left - gpio12 and gpio13. The ESP32-CAM board carries a camera, a LED flash, a microSD card slot, and a ESP32 microcontroller itself.įor the firmware upgrade we need the USB to TTL adapter, for example by AI thinker or FTDI, however, you are free to use any other USB to UART adapter. Today I want to show how to work with ESP32-CAM board using flespi. As technologies develop, microcontrollers get cheaper and more affordable for the public. Fridges, kettles, toys, smart sockets and switches, automatic gates - all of them are operated with the help of microcontrollers. Microcontrollers have spread everywhere sometimes even without us realizing that.
