The ESP32-CAM Breakout Board is a development accessory designed to simplify programming, powering, and interfacing the ESP32-CAM module. It breaks out essential pins to standard headers, provides stable power input, and often integrates USB-to-UART support (variant dependent), making firmware flashing and prototyping faster and more reliable. This board is ideal for computer vision, IoT camera projects, and rapid ESP32-CAM development.
