DFRobot Arduino Shields are the stackable functional boards for Arduino microcontrollers. The shields are easy to use and can be plugged on top of the Arduino PCB expanding its capabilities. These shields come with various functions for a variety of applications.
Bluno Beetle Shield
DFRobot Bluno Beetle Shield expands the Beetle's single analog and digital I/O pins to the 3-pin Gravity interface. This makes it easy to connect Gravity modules and gives more power and ground connections. A convenient external power supply and a 5-8V switch to turn the board on and off are included. To use the shield, the Bluno Beetle is stacked onto the shield's I/O pins and then soldered in place.
