Photorealistic close-up view of an electronics repair and debugging workstation. An authentic ESP32 board is connected via a micro-USB cable to a laptop keyboard. The red power LED on the ESP32 is lit. A modern yellow digital multimeter with sharp test probes is measuring the 3.3V and GND pins on the breadboard, showing "3.31 V" on its digital LCD screen. In the background, a neat engineer diagnostic checklist card with clear, crisp Russian text: "1. Питание: красный щуп 3.3V, чёрный GND" "2. Кабель: передача данных, не только зарядка" "3. COM-порт: драйвер CP2102 / CH340" "4. Скорость порта: 115200 бод" Crisp lighting, macro electronics photography, professional engineering look. Mehr sehen
