Micro bit V2

Features

• Onboard speaker
• MEMs Microphone with LED indicator
• Touch-sensitive logo
• Built-in sleep/off mode that means the board can be powered-down with batteries connected
• Discrete regulator that can supply up to 190mA of current to external accessories

Refinements

• Notched edge connector. To make it easier to connect things like crocodile clips and conductive thread
• Power LED indicator. In addition to the USB activity indicator, a power LED shows whether the micro:bit is powered on or off
• Gold plated antenna. To easily identify the radio/Bluetooth component
