LORDWORLD Micro:Driver Expansion Board for Micro:bit/UNIHIKER

SKU CH-E4T5-VD62R

Expands Micro:bit or UNIHIKER with 9 GPIO pins, 4 motor drivers, 8 servo ports and dual stepper support

  • Expands micro:bit with 9 GPIO pins for flexible prototyping
  • Drives up to 4 DC motors directly from the board
  • Controls 8 servos simultaneously for multi-axis projects
  • 4 motor channels reconfigure as 2 stepper motor drivers

LORDWORLD Micro:Driver Expansion Board

This expansion board connects to a micro:bit or UNIHIKER board and breaks out nine onboard GPIO interfaces for external circuits. It also integrates four motor drive channels and eight servo interfaces, with the motor channels configurable as two stepper motor drives. The board suits students and makers building robotics or automation projects that need multiple actuators from a single controller.

Motor and servo connectivity for micro:bit builds

The board requires a micro:bit or UNIHIKER module to operate and draws power through that host. It frees the developer from wiring discrete driver chips by providing ready-to-use motor and servo headers, reducing component count and breadboard space. Builders who need more than four motor channels or eight servo ports, or who require wireless communication not provided by the host, will need additional hardware.

Questions about this item

How many motors can the four driver channels control at once?

The board provides four motor driver channels that can run four DC motors simultaneously or be reconfigured to drive two stepper motors.

What heat should I expect from the driver ICs when all eight servos and four motors are active continuously?

The driver ICs will warm up under full load; adding a small heatsink or forced airflow keeps temperatures in a safe range during extended operation.
