Grove Cables
Grove Cables are designed to work with the Grove ecosystem - a 4-pin, modular, plug n' play connector standard designed to connect sensors and Grove modules to Grove-compatible development boards.
All Grove cables usually follow the same pinout. The usage of pins 1 and 2 can vary depending on the module being connected (I2C/Analogue/UART/Digital) however, I2C is arguably the most common usage:
- Pin 1 - Yellow (SCL/Dn/An/RX)
- Pin 2 - White (SDA/Dn+1/An+1/TX)
- Pin 3 - Red - VCC on all Grove Connectors
- Pin 4 - Black - GND on all Grove Connectors
Grove cables are available either buckled (with a little clip on them to hold the cable to the connector) or unbuckled (without the clip). Be sure to check which type you need for your project/hardware.
Grove was originally developed by Seeed, however has been adopted by many brands and hardware designers, with one of the largest being M5Stack.
