Micro:bit GPIO Breadboard Expansion Board | 22-Pin Breakout Adapter | USB & 5V Power Module
Description
The (SPIDER Automation) Micro:bit GPIO Breadboard Expansion Board is designed to bridge the gap between basic microcontroller education and advanced electronics prototyping. While the standalone Micro:bit board provides limited access via its primary alligator-clip rings, this expansion module breaks out all 22 GPIO pins, power connections, and grounds into a standard 0.1-inch pin header layout, allowing makers to harness the board’s full technical capabilities.
Equipped with an integrated USB power port and a dedicated 5V power supply input, the breakout board ensures your projects receive reliable energy when driving multiple components. The clearly labeled pin configuration and physical compatibility with standard 420-point and 840-point breadboards make it an indispensable tool for expanding sensor arrays, actuators, and complex logic circuits.
Key Features
- Full 22-Pin Breakout: Exposes all 22 General Purpose Input/Output lines for maximum circuit flexibility.
- Standard 0.1-Inch Spacing: Pin headers match standard breadboard columns for direct, solderless insertion.
- Dedicated Power Ports: Incorporates an onboard USB port and a 5V power supply input for stable voltage distribution.
- Clearly Labeled Silk-Screen: Every pin is explicitly marked on the PCB to simplify wiring and debugging.
- Secure Mounting Provisions: Built with standard M3 mounting holes for robust mechanical fixture inside enclosures.
- Breadboard Compatible Form Factor: Fits seamlessly onto 420-point and 840-point prototyping breadboards.
Benefits
- Maximized Hardware Potential: Move beyond basic alligator clips to connect a vast array of external electronic modules.
- Clean Prototyping Layout: Organizes messy jumper connections into a structured, easy-to-manage development surface.
- Reliable Power Delivery: Dedicated power inputs prevent voltage drops when powering external motors, servos, or sensors.
- Faster Circuit Assembly: Standardized pin spacing eliminates guesswork and reduces wiring errors during prototyping.
- Educational Efficiency: Ideal for classrooms and maker spaces looking to scale up student engineering projects.
- Durable Mechanical Build: Sturdy structural layout ensures long-term reusability across multiple maker projects.
Applications
- Advanced STEM Education & Labs: Expanding student coding projects with complex sensors, displays, and motor drivers.
- Breadboard Prototyping Circuits: Building and testing custom electronics setups using standard jumper wires.
- Robotics & Automation Builds: Connecting multi-axis servo controllers and autonomous sensor arrays to a Micro:bit core.
- IoT Environmental Monitor Hubs: Interfacing multiple temperature, humidity, and gas sensors through expanded GPIO lines.
- Wearable & Portable Tech Prototyping: Designing compact electronic test fixtures with secure power rails.
- Custom Hardware Testing: Rapidly evaluating peripheral modules before finalizing custom PCB layouts.
