Short Product Description

The Micro:bit Vertical Expansion Board is a plug-and-play breakout module designed to simplify sensor and servo connections for STEM robotics projects. Featuring a vertical card-edge slot, it provides clearly labeled, color-coded 3-pin headers, a built-in 3.5mm audio jack, and a micro USB port for external power. Ideal for students and makers using Python or MakeCode, this 66x66mm board eliminates the need for messy breadboard wiring.

Key Features

  • Vertical Edge Connector: Securely holds the Micro:bit upright to save workspace and improve the visibility of the LED matrix.
  • Standard 3-Pin Headers: Color-coded ports (Signal, VCC, GND) allow for instant, error-free connections to various electronic modules.
  • Selectable Voltage Jumper: Easily switch between 3.3V and 5V power outputs to ensure compatibility with a wider range of external sensors.
  • Integrated 3.5mm Audio Jack: Connect headphones or external speakers directly to pin P0 for instant sound output.
  • External Power Input: A built-in micro USB port provides dedicated power for high-draw components like servos and motors.
  • Programming Ready: Fully compatible with both graphical programming (MakeCode) and Python for versatile classroom learning.

Full Product Description

Plug-and-Play Sensor Expansion for STEM Projects

This breakout board instantly expands your Micro:bit's capabilities by converting its edge connectors into standard 3-pin headers (Signal, VCC, GND). This design allows you to connect various sensors, servos, and motors directly using standard jumper wires, completely eliminating the need for complex breadboard setups. The vertical mounting slot securely holds the Micro:bit upright, saving desk space and making the LED matrix easily visible during programming.

Built-in Audio and Dedicated Power Management

The board features a dedicated 3.5mm audio jack internally routed to pin P0, allowing you to plug in headphones or speakers instantly for music and sound projects. Additionally, it includes a micro USB port to supply external power to heavy loads like servos, preventing the Micro:bit from resetting due to current drops. A selectable voltage jumper allows you to switch between 3.3V and 5V logic to match your specific external modules.

Technician Tip

When driving multiple servos or high-current motors for a robotics project, always connect an external 5V power supply to the expansion board's micro USB port rather than relying solely on the Micro:bit's USB power. This ensures stable operation. If you are sourcing sensors for a school STEM project, visit Sun Cheong Computer Co. Ltd. in Sham Shui Po—our staff can help you select compatible 3-pin modules that plug directly into this board.

FAQ Section

Is this expansion board compatible with both Micro:bit V1 and V2?

Yes, the vertical edge connector is universally designed to support both BBC Micro:bit V1 and V2 models perfectly.

Do I need to solder anything to use this breakout board?

No, this is a completely plug-and-play module. All headers, jacks, and slots are pre-soldered, allowing you to connect sensors instantly using standard female-to-female jumper wires.

Why is there a micro USB port on the expansion board?

The micro USB port provides external power to drive high-current components like servos and motors. This prevents the Micro:bit from crashing or resetting when external modules draw too much power.

How do I output sound using this board?

You can plug standard headphones or a speaker directly into the built-in 3.5mm audio jack. This jack is internally routed to pin P0, which is the default audio output pin in MakeCode and Python.

Can I buy compatible 3-pin sensors at your Sham Shui Po store?

Yes, we stock a wide variety of compatible 3-pin sensors, servos, and jumper wires at our physical store for immediate pickup to complete your STEM project.
