The Gravity IO Expansion Shield breaks out all GPIO pins from the LattePanda into Gravity-compatible 3-pin colour-coded connectors, providing plug-and-play access to hundreds of Gravity sensors and modules. Each pin includes VCC and GND, eliminating the need for separate power wiring.
The shield also adds a flexible power solution — use a 7–12 V supply via the 2.1 mm DC jack or 2-pin terminal to power both the LattePanda and connected devices, with up to 5 A available at the 5 V output. An 8×8 prototyping pad area is included for custom circuitry.
Key Features
- Gravity 3-Pin Interface – Colour-coded connectors compatible with the full Gravity sensor range
- 14 Digital + 6 Analogue Ports – Full GPIO breakout with VCC and GND on each pin

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- 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.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
