A small, irregularly shaped green printed circuit board (PCB), approximately 5-7 cm in length, rests on a light grey, slightly textured surface. The PCB features a black 3.5mm audio jack connector at one end and a metallic micro-USB charging port at the other. A circular, silver vibrator motor with a black eccentric weight is connected to the PCB via red and black wires. Numerous surface-mount device (SMD) components, including integrated circuits, resistors, and capacitors, are populated across the PCB's surface. The background surface displays minor scratches and a faint, elongated smudge. The lighting is even, indicating an indoor setting. The image provides no visual information to determine its location within the city of Wrocław, Poland, or any other specific geographic area. No people are present, and no actions or interactions are depicted.
