Booster Quick Start Handbook

“MuseLab Booster” is one of the latest and most powerful IoT shields that is presently available in the market. The shield (with the MuseLab edge connector) is developed by MuseLab. When you insert your micro:bit into the edge connector, your micro:bit will be WIFI enabled. In other words, micro:bit is able to access the Internet using our MuseLab shield.

There is a screen, 3v/5v switch and a WIFI module on the shield. The screen is indeed very useful – it shows the information like IP address and the battery status. For the switch, you can alter the output voltage of the 4 i/o pins.

There are 4 input/output pins, 1 I2C pin for you to do the project! You can insert different input like light and sound sensors. For output, you can use LED, buzzer, servo and so on.
