Gravity: Bluno Beetle Shield

The Gravity: Bluno Beetle Shield is a compact expansion board designed specifically for the miniature Bluno Beetle microcontroller. It provides plug-and-play Gravity pinouts to simplify sensor and actuator wiring. This board is an ideal choice for students, makers, and hobbyists developing space-constrained robotics and wearable electronics projects.

Dedicated Bluno Beetle expansion

The shield mounts directly to the Bluno Beetle, expanding the micro board's available pinouts while maintaining a compact footprint. It enables quick prototyping without sacrificing the small size needed for portable builds.

Eight digital and analogue channels

The board breaks out 4 digital channels and 4 analogue channels for broad peripheral compatibility. This layout allows simultaneous connection of diverse input sensors and output devices.

Standard 3-pin Gravity connectors

Integrated 3-pin Gravity headers provide dedicated signal, power, and ground connections for each pin. This enables straightforward, solderless connection to any Gravity-compatible module.

External power input and switch

The shield accepts an external power input ranging from 5V to 8V to drive attached components reliably. An onboard power switch allows users to easily toggle power to the system without disconnecting cables.
