2.5.7.1 Grove I2C Interface (J4)

The J4 connector provides a dedicated I2C interface operating at 3.3V logic levels. This Grove port connects directly to the I2C2 bus (I2C2_SCL and I2C2_SDA) of the AM335x processor, with unpopulated footprints for optional 4.7kΩ pullup resistors providing reliable communication with a wide range of I2C modules.

This interface supports numerous Grove I2C modules from the Seeed ecosystem. Compatible devices include environmental sensors for measuring temperature, humidity, and pressure; motion and position sensors such as accelerometers and gyroscopes; display modules including OLED and LCD screens; and various interface adapters and port expanders. The standardized connection format eliminates the need for complex wiring or breadboards when prototyping with these components.
