Overview

The DFRobot Gravity IO Expansion Shield is a multifunction expansion board for Arduino that helps simplify wiring and module connections. It is designed to work with Gravity modules using color-coded interfaces, reducing the need for breadboards, soldering, or messy jumper wiring.

The board is compatible with Arduino UNO R3 and UNO R4, and it also supports use with non-Gravity modules through DuPont wires. It includes an Xbee socket, APC220 wireless interface support, a UART fast toggle switch, a 3.3V selection jumper, and servo power protection.

According to the provided specifications, the shield supports 7-12V input on PWR_IN, 4.8-6V on SERVO_PWR depending on the servo, and works with 5V/3.3V compatible modules. It supports I2C, SPI, Xbee (Xbee Pro), Bluetooth, and APC220 interfaces.
