![]() In this tutorial we will use a Nucleo board from ST Microelectronics as a 5V source and will also use its 3.3V UART interface provided by the on-board ST-Link to receive the text output from the ESP32-CAM module. See the picture below for details (courtesy of Seeed Studio): As the ESP32-CAM board does not come with a USB connector, you would need to use an external 5V power source. Olimex ARM-USB-OCD-H or Segger J-Link): ESP-CAM Pin In order to get JTAG debugging to work, we would need to connect the following pins of the ESP32-CAM module to a compatible JTAG debugger (e.g. Before you begin, ensure you have installed Visual Studio and VisualGDB 5.4. We will use VisualGDB to clone the ESP32 Arduino Camera example and then modify it to automatically take pictures in a loop and upload them via HTTP to a specified server. This tutorial shows how to create a basic project for the ESP32-CAM module and use the JTAG interface to debug it.
