Gravity: LED Switch - module with self-locking button and LED backlight (blue)

A 24-channel input/output port expander module controlled by an I2C interface. It was based on the CH423 chip and equipped with a Gravity connector. DFRobot DFR0979

This encoders are designed for DFRobot 3PA and AWD Rovers. It can give you the rotation degree of the wheels. Encoder uses non-contact method to convert the angular displacement signals. Best fit with Micro DC Geared Motor. SEN0038

The Gravity Occupancy Sensor uses 24 GHz FMCW radar technology, enabling precise presence detection at a distance of up to 8 meters and movement and distance measurement up to 12 meters. Thanks to its high resistance to environmental interference, it works reliably regardless of light, temperature or dust, effectively detecting both static and dynamic objects. Compatibility with Arduino, ESP32, Raspberry Pi and a simple Gravity interface make it an ideal solution for intelligent lighting, building automation and security systems. DFRobot SEN0610

The expansion board is designed for DFRduino M0 or Bluno M0 sets. The board has 31 GPIO pins (including 6 PWM and 6 ADC inputs), UART, I2C and SPI interfaces. The pins are color coded according to the Gravity standard. DFRobot DFR0412
