The 3 Watt 8 Ohm Mini Speaker with JST-PH2.0 Interface is a compact yet powerful audio solution designed for DIY electronics, robotics, and embedded projects. With a full-range frequency response of 500Hz–20kHz, it delivers clear and balanced audio for voice prompts, sound effects, or background music. Built with an internal magnetic circuit and a durable non-paper diaphragm, this mini speaker ensures long-lasting performance in a small form factor. Its JST-PH2.0 2-pin connector makes it easy to interface with Arduino, Raspberry Pi, and other microcontrollers, offering quick integration without soldering. Measuring just 31×28×15mm and weighing only 30g, it is perfect for robotics, gaming devices, smart terminals, and compact embedded systems where size and reliability matter. Featured By RoboticsBD.
