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.
