Grove Cable Pigtail - 2mm pitch 100mm long

If you want to connect to a board or breakout with a Seeed Grove connection, this 100mm long 4 - wire cable is your ideal choice. It comes with a Grove connector and four bare wires. When using 3V - only sensors, be careful with the voltages on the power/signal pin, as many Grove boards are 5V logic, similar to Arduino UNO - compatibles. The cable has specific color - coded wires: black for GND, red for V+ (power can be 3V or 5V depending on the microcontroller board), blue for SDA, and yellow for SCL. Note that these are not JST cables and won't fit in JST PH sockets.

Using this cable is easy. First, if you want to connect it to a board or breakout with a Seeed Grove connection, just plug the Grove connector into the appropriate slot. When you're using sensors that only work with 3V, make sure to check the voltage on the power and signal pins, because some of the Grove boards use 5V. As for the wire colors, black is for ground, red is for power (the voltage depends on your microcontroller), blue is for SDA, and yellow is for SCL. Keep in mind that you can't use this cable in JST PH sockets. To maintain this cable, store it in a dry place and avoid bending it too sharply, which could damage the wires inside.
