EC Buying Micro:bit V2.2 Development Board Robot Kit for Python Programmable Micro USB
- Auditory Interaction Revolution: Comes with "Mouth" and "Ears" : the biggest highlight of V2.2 is the built-in speaker and microphone. Students can directly make the micro: bit sing, speak, or create "voice controlled lights," "clap counters," and "noise detectors" without connecting any external wires or headphones. The LED light next to the microphone can also visually display the recording status, protecting privacy.
- The explosion of computing power and AI potential (performance improvement by 4-8 times) : Thanks to the Cortex-M4 processor and 128KB RAM (8 times that of V1 version), V2.2 not only runs code more smoothly, but also handles complex computing tasks. This enables it to run micro machine learning models, such as training it to recognize specific speech commands (such as "turn on the light") or gesture actions, leading students into the AI era.
- The "invisible" third button: The gold logo on the front of the touch logo is no longer just a decoration, but a capacitive
