    Try adding the microbit "servo" extension which uses P0, P1 and P2. This is the “standard” microbit extension to control servo motors. You do not need the older Maqueen Plus “SERVO” command. If you use the “Servo” P0, make sure to switch off the P0 “sound” switch next to the Power switch on the Maqueen Plus V2.0 board. Make sure to connect your servo to the one of the 3 pin connections labelled “Servo” - P0 P1 P2. Do not use the P0, P1, P2 to the left of the “Servo” pins as they only supply 3 volts. Also note that the servos are using VBAT (the battery voltage). I have the Lithium Battery version with a nominal voltage of 3.7 volts which is a bit low for most servos. You should have 4 volts or more for reliable servo operation. Good luck.

    Hello,

     

    This reply is a bit late, but I just had the same problem. Try adding the microbit "servo" extension which uses P0, P1 and P2.
