  • Operating Voltage: 3.3V~6V

  • Rated Voltage: 4.8V

  • Rated Current: 200mA

  • Blocked Rotor Current: 1800mA

  • Maximum RPM: 200rpm

  • Stopping Torque: 1000g

  • Weight: 44g

  • Connector: Red and Black Motor Connector

Special Features:

  • Uses an axle connector for output:

    • Connect to axles of different lengths to better suit your needs

  • Dual outputs:

    • Has outputs axles on both sides

  • High speed

    • About 3 times the RPM of the GeekServo 9g Motor

  • Carbon Brushed Motor

    • Longer Lifespan and Lower Noise

Dimensions

In Lego units:

  • Length: 10

  • Width: 5

  • Height: 3

  • Output Axle: Technic Axle

In mm units:

  • Length: 72mm

  • Width: 39mm

  • Height: 23.8mm

Connection

In this demonstration, Robotbit is used. It is also possible to use an Armourbit.

Robotbit


Connect the cable to the motor.

FAQ

1: The Micro:bit does not react when I click the programming blocks.

Make sure the Micro:bit has been connected to the Kittenblock and then try flashing the firmware.
