Notes on use

• The servo interface can only use the blue 9g small servo or Geekservo servo, and it is forbidden to connect the high current servo.
• The DC motor interface is only suitable for Miaojia TT motor or Geekservo motor. It is forbidden to connect high current motor.
• The buzzer is multiplexed with Microbit's P0. When using it, check whether the toggle switch on the bottom is on. (Buzzer switch at hand turns on the buzzer by default)
• To use each module, motor, and servo, you must connect the Powerbrick battery box, otherwise the module will not be used properly because of insufficient current.
