Some DFRobot Gravity modules may also appear in the sensors or electronic modules categories because products are organized by application as well as by product family. Broad categories help customers browse the manufacturer's range without navigating numerous narrow subcategories.
DFRobot Gravity – A Unified Connector System for Peripheral Modules
DFRobot Gravity is a family of sensors and peripheral modules based on a standardized connection system. Many analog and digital modules feature 3-pin PH2.0 connectors, while devices using the I2C bus commonly use 4-pin connectors. This simplifies connecting compatible modules to development boards and reduces the need for individual jumper wires. The Gravity ecosystem includes not only sensors but also displays, sound generators, control modules, input/output expanders, relays and actuators. Examples include DFRobot Gravity modules based on the MCP23017 and TCA9548A chips, designed to expand GPIO connections and I2C interfaces. However, the shared connector format does not guarantee universal compatibility. Supply voltage, signal type, pin assignment and controller interface support must still be verified.
DFRobot Gravity and Fermion Sensors for Environmental Monitoring
One of DFRobot's main areas of specialization involves sensors for measuring physical, chemical and environmental parameters. The range includes modules for temperature, humidity, pressure, light, acceleration, motion, liquid level and distance measurement. DFRobot also supplies pH, electrical conductivity, soil moisture and air quality sensors for measurement stations, water monitoring systems and automated irrigation installations. The Gravity series focuses on convenient wired connections, while DFRobot Fermion includes compact modules designed for integration into prototypes and embedded systems. Depending on the model, communication uses analog or digital signals, UART or I2C.
DFRobot Electronic Modules, Power Converters and FireBeetle Platforms
DFRobot also develops circuits for powering and controlling electronic devices. The range includes step-down and step-up DC/DC converters, battery charging modules, analog-to-digital converters (ADC), digital-to-analog converters (DAC) and interface converters. The selection is complemented by DFRobot FireBeetle development boards, including ESP32-based models designed for IoT devices and wireless communication. Selected boards support Wi-Fi, Bluetooth and protocols used in smart home systems. FireBeetle expansion modules allow additional interfaces and peripherals to be connected. DFRobot components support wireless data loggers, measurement devices and automation controllers.
DFRobot Mechanics and Educational Robots – Maqueen, Boson and Mobile Platforms
DFRobot supplies mechanical components for building robots and mechatronic devices. Available products include servos, geared motors, robot chassis, wheels, sensor mounts and mechanical actuating components. DFRobot Maqueen robots, designed for use with micro:bit, are among the manufacturer's educational products and support exercises involving motor control, line following and obstacle detection. The manufacturer also develops modular Boson kits and Romeo robot controller platforms. Combining mechanical components, motor controllers, sensors and programming tools enables practical exercises in robotics, automation and mechatronics. DFRobot products are used in schools, technical workshops and independent electronics projects.
