Modern IoT device, futuristic laboratory setting, sleek metal workbench, various microchips, wires, circuits, and electronic components scattered around, a large screen displaying system architecture diagrams, flowcharts, and coding interfaces, a designer wearing a white lab coat, glasses perched on the end of their nose, messy brown hair, holding a stylus, standing in front of the workbench, intense facial expression, dim warm lighting, shallow depth of field, focus on the designer's hands and the screen, blurred background with subtle hints of futuristic laboratory equipment.
