If you'd like to make a connection to a board or breakout with Seeed Grove connection, this 100mm long 4-wire cable is fitted with a Grove connector and four bare wires.

Please note you will have to watch for voltages on the power/signal pin when using 3V-only sensors, because Grove boards that are 5V logic like many Arduino UNO-compatibles.

The colors are:

• Black for GND
• Red for V+ - Can be 3V or 5V power depending on the microcontroller board!
• Blue for SDA
• Yellow for SCL

Note these are not JST cables, and won't fit in JST PH sockets!
