DFRobot Gravity: Bluno Beetle Shield Micro Controller Board Electronic Hobby Kit

Unlock the full potential of your Bluno Beetle with the Bluno Beetle Shield. This expansion shield converts the Beetle’s single analogue and digital I/O pins into four 3‑pin Gravity interfaces, giving you more power and ground connections and making it simple to plug in Gravity sensors and modules—no messy wiring required. Just stack the Bluno Beetle onto the shield’s I/O pins and solder in place for a compact, robust assembly. The onboard power switch and external Vin input (5–8 V) let you conveniently power the board on or off and integrate it into a wide range of projects. Four 3 mm mounting holes ensure secure installation in enclosures, robots, or prototypes. Features: - 4 x Digital I/O pins: D2–D5 - 4 x Analog input pins: A0–A3 - 4 x Gravity 3‑pin interfaces (signal, VCC, GND) - Vin input range: 5–8 V - Onboard power switch - 4 x 3 mm mounting holes for easy fixing in your project
