Gravity: IO Expansion & Motor Driver Shield - an expansion board for Arduino

Expansion board for Arduino, allows easy connection of XBee modules, has separate outputs for I2C, SPI and UART buses. The built-in 3.3V voltage stabilizer and operating mode switch make it easier to program the Arduino when the XBee module is connected to the sockets. DFRobot DFR0265

The Bees shield is compatible with Arduino boards such as UNO R3 and Leonardo it has a large prototyping shield giving you plenty of space to experiment and add extra components to your project. Thanks to its uniform interface, there are a huge number of devices compatible with the xBee socket: xBee, WiFi xBee, Bluetooth Bee, zigBee, etc. DFR0210

The shield allows for easier connection of cables to the Arduino UNO R3 board. Thanks to the screw connectors, it is possible to fast and secure the cable, goldpin connectors allow you to easily connect the servo, and the built-in female connectors allow you to put additional Arduino shields
