Description The Grove Base Cape for BeagleBone v2.0 turns the BeagleBone expansion headers into 12 convenient Grove connections for rapid, solder-free prototyping. It provides dedicated interfaces for I2C, UART, analog input, and digital I/O, making it easier to connect sensors, actuators, displays, and communication modules. A switch selects 3.3 V or 5 V output for connected Grove modules. The cape also includes a 256 kb EEPROM, configurable cape addressing, and a USER button for flexible development and multi-cape setups. Features 12 Grove connectors for fast plug-and-play development 4 I2C, 2 analog, 2 UART, and 4 dedicated digital I/O connectors UART1 and UART4 pins can also be used as digital I/O Switchable 3.3 V or 5 V output voltage Four selectable cape EEPROM addresses from 0x54 to 0x57 256 kb CAT24C256WI serial EEPROM Onboard USER button and write-protection control Specifications Compatible platform BeagleBone platform Grove connectors 12 I2C connectors 4 Analog connectors 2 UART connectors 2 (UART1 and UART4) Dedicated digital connectors 4; UART1 and UART4 pins can also provide digital I/O Output voltage 3.3 V or 5 V, switch selectable Maximum output current 500 mA at 3.3 V; 500 mA at 5 V EEPROM 256 kb CAT24C256WI serial EEPROM Cape address options 0x54, 0x55, 0x56, or 0x57 Dimensions 70 x 50 mm Applications BeagleBone sensor and actuator prototyping Home automation and environmental monitoring Robotics and motion-control projects Data acquisition and educational electronics Rapid proof-of-concept development with Grove modules Product List 1 x Grove Base Cape for BeagleBone v2.0 Other Content When installing the cape, align the two notches on its edge with the matching notches on the BeagleBone board to ensure the correct orientation. Select the required 3.3 V or 5 V output before connecting Grove modules. For systems using multiple capes, set the two address switches so each cape EEPROM uses a suitable address between 0x54 and 0x57. Resources Grove Base Cape for BeagleBone v2.0 Wiki and Getting Started Guide Grove Base Cape for BeagleBone v2.0 Schematics FAQ How many Grove connectors are available? The cape provides 12 Grove connectors: 4 I2C, 2 analog, 2 UART, and 4 dedicated digital I/O connectors. Can the Grove output voltage be changed? Yes. The onboard voltage switch selects either 3.3 V or 5 V for connected Grove modules. Can several capes be used without an EEPROM address conflict? The two cape-address switches select one of four EEPROM addresses from 0x54 to 0x57, which helps avoid address conflicts in multi-cape configurations. Do the UART connectors support digital I/O? Yes. UART1 and UART4 share pins that can also be configured as digital I/O when required by the application.
