BBC Micro: bit Expansion Breakout Adapter Board

Full Edge Pin Breakout Access: Breaks out all edge pins of the BBC micro:bit board into standard 2.54mm pitch headers, providing convenient access to GPIOs, power rails, PWM, SPI, and I2C lines.

Vertical Edge Connector Slot: Features a high-durability edge socket for effortless vertical insertion and removal of micro:bit V1 or V2 boards without risk of pin bending.

Color-Coded Header Layout: Pin headers are intuitively color-coded (Signal, Power VCC, and Ground GND) to simplify jumper wire connections and reduce wiring errors during prototyping.

Onboard Power Bus Options: Delivers dedicated 3.3V and 5V power rails with external DC jack / USB auxiliary input support to easily power external servos, sensors, and relays.

Breadboard & Cable Friendly: Designed for seamless integration with standard breadboard jumper cables, Dupont wires, and external sensor modules.

Module Construction: Built on a multi-layer FR-4 glass epoxy printed circuit board featuring gold-plated contacts and durable surface-mount pin headers.

Power Supply & Operating Voltage: Accepts power directly from the host micro:bit or an external auxiliary power supply. Ensure external voltage levels match your connected sensors (3.3V or 5V) before turning on power.

Handling Precautions: Hold carefully by the outer circuit board edges. Avoid touching connector pins or circuit traces directly to prevent electrostatic discharge.

Environmental Limits: Operating temperature range spans 0°C to +70°C. Keep protected from static discharge, conductive metal dust, and liquid moisture.

Essential Classroom & Prototyping Companion: Position as a must-have expansion adapter for students, teachers, and makers looking to connect standard sensors and breadboards to the micro:bit.

Eliminates Alligator Clip Clutter: Highlight as a clean, organized alternative to messy alligator clip leads, allowing for reliable and complex electronic circuit builds.

Recommended Cross-Sell Add-ons: Pair with BBC micro:bit V2 Boards, 3V/5V Sensor Modules, Servo Motors, and Male-to-Female Jumper Wires.

Ideal for STEM Robotics & IoT: Perfect foundation for building custom smart home nodes, robotic chassis controllers, environmental monitoring stations, and interactive physical computing setups.
