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 is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- 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.
