Unlike other ESP Development Boards, the ESP32-CAM has no USB connector to connect it to a computer. This might be confusing for beginners when they try to program this development board for the first ...

ESP32-CAM-Arduino-and-OpenCV The ESP32-CAM is a compact and affordable development board designed for applications involving video streaming, image capture, and low-power IoT projects.

This project creates a two-way connection between two ESP8266 modules using the ESP-NOW protocol. All data arriving on the module UART0 port is sent via ESP-NOW to the second module and then sent via ...

In it, he shows an example of using all three ESP32 UARTs from an Arduino program. He calls the third port “secret” although that’s really a misnomer.

By flashing the esp-link firmware into your ESP8266, you talk directly to the microcontroller over WiFi as if it were connected by a serial cable: the ESP8266 becomes a totally transparent WiFi ...
