The Grove Cape for Beaglebone from Seeed Studio is an expansion board designed to help you quickly prototype with the Beaglebone Black. The board provides remaining Grove connectors for a seamless connection to an array of over 70 Grove modules for easy integration of sensors, actuators, and communications devices like wireless transceivers. The board also includes an onboard Grove I2C port for extending connections to even more Grove modules. A dedicated 3.3V supply from the Beaglebone eliminates the need for an external power supply for the Grove modules connected. The Grove Cape is a great way to quickly add sensors or devices to a project without the hassle of breadboards, jumper wires, and custom circuitry.
