<br />
== Technical overview ==<br />
* Integrates the audio power amplifier IC NS8002, a high-quality speaker, and a headphone jack.<br />
* Dimensions: 36.52 mm × 30.72 mm.<br />
* Operating voltage: 2.0 V to 5.5 V.<br />
* The switch selects the playback device: right position routes to the headphone output; left position uses the onboard speaker.<br />
* The rotary knob controls volume: turning it left increases volume, turning it right decreases volume.<br />
* Connects using either DuPont wires or alligator clip wires, both included in the package.<br />
* Pin mapping: 3V3 (power positive), GND (ground), and pin 0 (audio output).<br />
* Officially recommended programming paths are TypeScript (graphical, makecode.microbit.org) or MicroPython (online or offline via the Mu application).<br />
