Description

The Micro:bit GPIO Expansion Board significantly enhances the BBC micro:bit’s capabilities by providing comprehensive access to its underlying hardware. While the micro:bit natively offers only three digital/analog input/output rings for use with alligator clips, this expansion board transforms it into a more versatile development platform. It meticulously breaks out all 60 GPIOs, along with dedicated power and ground pins, into a standard 0.1-inch (2.54mm) pin formation. This allows for direct connection to breadboards, jumper wires, and a wide array of electronic components and modules, vastly expanding prototyping possibilities.

Designed for convenience and robust functionality, the board features a dedicated power indicator light that illuminates red when powered, providing instant operational feedback. An integrated miniature buzzer is included, fully programmable within the MakeCode environment, enabling projects with audible alerts or simple tunes. All available pins are extended without reservation, ensuring maximum flexibility for makers, educators, and embedded developers seeking to integrate complex circuits or utilize a greater number of peripherals with their micro:bit.

Key Features

  • Breaks out all 60 GPIO pins, power, and ground from the micro:bit to 0.1" headers.
  • Equipped with a red power indicator light for clear operational status.
  • Includes an integrated miniature buzzer, programmable through the MakeCode music column.
  • Retains full access to all micro:bit pins without any exclusions.
  • Compact design with a 40P horizontal socket for space-efficient integration.
  • PCB thickness of 1.6mm ensures durability and stable connections.

Applications

  • Educational STEM projects requiring extensive I/O.
  • Robotics and automation where multiple sensors/actuators are needed.
  • IoT prototyping using micro:bit as a central controller.
  • Interactive art installations and wearable technology.
  • Rapid prototyping and circuit design with breadboards.

Frequently Asked Questions

What is the primary function of this Micro:bit GPIO Expansion Board?

This expansion board extends the BBC micro:bit's capabilities by breaking out all 60 of its internal GPIO, power, and ground pins to standard 0.1-inch (2.54mm) headers. This allows for easy connection to breadboards, sensors, actuators, and other electronic modules, significantly enhancing the micro:bit's prototyping potential.

How is the onboard miniature buzzer controlled?

The miniature buzzer on the expansion board is fully programmable through the Micro:bit's MakeCode editor. Users can access the 'music' column in MakeCode to write code that generates sounds, tones, or melodies, making it ideal for adding audible feedback to projects without requiring external components.

What is the operating voltage and maximum output current of the board?

The Micro:bit GPIO Expansion Board operates at a standard 5V, consistent with many common development platforms. It supports a maximum output current of 40 mA, which is suitable for driving typical low-power sensors, LEDs, and other small components directly from the GPIO pins.

Is this expansion board compatible with all versions of the BBC micro:bit?

Yes, this GPIO expansion board is designed to be compatible with all standard versions of the BBC micro:bit, including V1 and V2. It physically connects to the micro:bit's edge connector, providing a universal breakout solution for micro:bit users across different revisions.
