SPIDER Automation Micro:bit T-Type GPIO Expansion Board | Breadboard Breakout Adapter
Description
The SPIDER Automation Micro:bit T-Type GPIO Expansion Board is an indispensable tool for students, educators, and makers looking to expand their BBC micro:bit experiments beyond standard alligator clips. While the standalone micro:bit provides only three accessible ring connections, this T-shaped expansion board breaks out all 21 GPIO lines, power rails, and ground pins into a clean, easy-to-read 0.1-inch pin header formation.
Engineered specifically for seamless breadboard integration, the T-shape design straddles standard 420-point and 840-point solderless breadboards perfectly, allowing you to build complex circuits without messy wiring. Featuring a dedicated 5V power supply port, an auxiliary USB power input, and clearly silkscreened pin labels, it ensures rapid, error-free prototyping for sensors, LEDs, motors, and peripheral modules.
Key Features
- Ergonomic T-Shaped Form Factor: Specially designed layout bridges the micro:bit directly onto breadboards without blocking adjacent rows.
- Complete 21-Pin Breakout: Brings out all 21 micro:bit GPIO lines, power terminals, and grounds to standard 0.1” pin headers.
- Clear Silk-Screened Labels: Every pin is clearly marked to prevent wiring mistakes during circuit assembly.
- Breadboard Compatible: Matches standard spacing for effortless insertion into 420-point and 840-point solderless breadboards.
- Auxiliary Power Options: Features an onboard 5V power supply port and USB power connection to support high-draw external modules.
- Mechanical Mounting Support: Includes standard M3 mounting holes for secure attachment to project chassis or test benches.
Benefits
-
- Simplifies Circuit Prototyping: Eliminates clumsy jumper wire tangles by letting you plug your micro:bit straight into a standard breadboard.
- Enhances Power Delivery: Dedicated 5V and USB power ports ensure stable voltage distribution for servos, motors, and sensors.
- Ideal for Educational Labs: Clear labels and robust build quality make it perfect for classroom environments and STEM learning.
- Unlocks Full GPIO Access: Grants immediate access to all micro:bit input/output lines for advanced physical computing projects.
Applications
- Solderless Breadboard Experiments: Building temporary electronic circuits with resistors, LEDs, pushbuttons, and transistors.
- STEM & Classroom Education: Teaching children and beginners basic electronics, wiring, and microcontroller programming.
- Sensor Interfacing: Connecting temperature sensors, light detectors, ultrasonic modules, and LCD screens.
- Small Robotics Prototyping: Wiring mini DC motors, buzzers, and servo controllers safely to a micro:bit controller.
Package Includes
