The Bluno Beetle Shield is a compact and convenient expansion board designed specifically for the Beetle BLE (Bluno Beetle). It transforms Beetle's basic I/O interface into Gravity-compatible 3-pin connectors (signal, VCC, GND), making it much easier to connect DFRobot’s Gravity sensors and modules.
This shield provides more stable power and ground pins, and includes a switchable external power supply (5–8V), allowing for easier powering and control. Simply solder the Beetle BLE board onto the shield, and it’s ready to use with all Gravity modules.
