A 100 mm pigtail cable with a Seeed Grove connector on one end and four bare wires on the other, for connecting Grove-compatible boards and breakouts to custom wiring.
Specifications
- Connector – Grove (2 mm pitch), 4-pin
- Length – 100 mm
- Wires – 4 (bare ends)
Wire Colours
- Black – GND
- Red – V+ (3.3V or 5V depending on host board)
- Blue – SDA
- Yellow – SCL
Note: This is a Grove connector (2 mm pitch), not JST PH — it will not fit JST PH sockets. Check the power/signal voltage when connecting 3.3V-only sensors, as many Grove host boards run at 5V logic.
Jargon buster
Plain-language definitions for the technical terms used above.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- Grove
- Grove is a standardised 4-pin plug-in connector system for sensors and modules that avoids soldering and jumper wires, with different cable types carrying I2C, UART, analogue or digital signals. When a product is Grove-compatible it can be quicker to connect supported modules, provided the connector type, signal and voltage all match.
- JST PH
- A small keyed plug-and-socket connector with 2 mm pin spacing, often used for low-power electronics connections. You need the correct JST PH cable, and its current rating limits how much power should be passed through it.
- SCL
- The clock line used by the I2C bus to keep data transfers timed between a controller and connected devices. When wiring I2C, SCL must be connected to the SCL pin on every device sharing the bus.
- SDA
- The data line used by the I2C bus to carry information between a controller and connected devices. When wiring I2C, SDA must be connected to the SDA pin on every device sharing the bus.
