The Bluno Beetle Shield is a compact and convenient expansion board designed specifically for the Beetle BLE (Bluno Beetle). This Bluno Beetle Shield expansion board 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 to your Beetle BLE project. This shield provides more stable power and ground pins, and includes a switchable external power supply (5–8V), allowing for easier powering and control of the expansion board. Simply solder the Beetle BLE board onto the shield, and this Bluno Beetle Shield is ready to use with all Gravity-compatible modules. Features Expands Beetle’s I/O pins to Gravity 3-pin format with the Bluno Beetle Shield Provides more power & ground terminals for external Beetle BLE modules Includes a 5–8V power supply input and power switch on the shield Ensures easy Gravity-compatible module attachment, no jumper mess Perfect match for wearable, prototyping, and low-space Arduino BLE applications Compact, stackable expansion board design for embedded setups How It Works Align the Beetle BLE board over the Bluno Beetle Shield’s I/O pin headers Solder Beetle BLE in place for a secure physical and electrical expansion board connection Plug Gravity-compatible sensors/modules directly into the Bluno Beetle Shield 3-pin ports Use the power switch to control the external 5–8V input for your Arduino BLE project Ideal For Prototyping with Gravity sensors and Bluno Beetle Shield Wearable tech using Beetle BLE Low-profile Arduino BLE applications with this expansion board Beginner-friendly setups with minimal wiring on the Bluno Beetle Shield What's in the Box Gravity: Bluno Beetle Shield ×1 Compatibility Works with Beetle BLE (Bluno Beetle) expansion board Supports all DFRobot Gravity 3-pin modules (sensors, actuators, displays) Reference Wiki (Bluno Beetle Shield ) Schematic Layout SVG file
