This is the GrovePi+ shield, which allows you to use the grove 4 pin system with your RaspberryPi board. It is compatible with both the generations Raspberry Pi model B, B+, A, and RPI 2 boards. The GrovePi + board features faster SPI and more reliable UART connections along with a more simplified procedure to update the firmware. Other new features include mounting holes for the model B+ and B and also a space for the camera cable to fit through. Please note that this kit does not include any Raspberry Pi board. We also sell the grovepi+ board as part of a grove starter kit.
