DFRobot Gravity: 4Pin I2C/UART Sensor Cable for Arduino is compatible with standard breadboard pin pitch for convenient DIY connection. This cable features a PH2.0-4p connector on one side and an XH2.54 DuPont port on the other end. The standard gravity series 4-pin cable features a 50cm length and operates at up to 50V(max) and 1000mA(max) supply range. The sensor cable uses color code design to distinguish between the positive and negative power supply, I2C port, and UART port.
