2" GI Plug

Gi Plug 2 provides up to 8 extra GPIO ports that are exposed via the GPIO header. The pins map to the Raspberry Pi’s standard GPIO layout (BCM numbering) and are accessible through the hat for use with sensors, modules, or small actuators.

Yes. Gi Plug 2 is compatible with Raspberry Pi 4 and works with other Raspberry Pi models that use the 40-pin GPIO header.

No soldering or modifications are required. Gi Plug 2 is a plug-and-play HAT that attaches directly to the Raspberry Pi’s GPIO header.

Yes. Gi Plug 2 has a power switch that lets you turn the Raspberry Pi’s power on or off without disconnecting cables.

Gi Plug 2 includes a built-in voltage regulator to help stabilize and protect the Pi from power surges, contributing to safer operation of the GPIO circuitry.

Yes. The 8 extra GPIO ports are designed for connecting sensors, small modules, and other low‑current peripherals, making it convenient for prototyping and compact projects.

Use cases include sensor monitoring and data logging, small robotics control, home automation sensors, and any project that needs additional I/O without adding complex wiring or soldering.

Step 1: power off the Raspberry Pi. Step 2: align Gi Plug 2 with the Raspberry Pi’s GPIO header. Step 3: press gently to seat it. Step 4: power the Pi back on. Step 5: test the new pins in software (for example with a simple GPIO script) to confirm operation.

Compared to other GPIO expansions on Fepy, Gi Plug 2 offers a compact HAT form factor with a built‑in voltage regulator and power switch for convenient power control.

Gi Plug 2 combines extra GPIO ports, a built‑in regulator, and a power switch in a single compact HAT, simplifying prototyping and space‑constrained builds. It’s priced to reflect the convenience and protection features, and you can look for bundles or compatible accessories on Fepy’s Gi Plug listings.

Always power off the Pi before installing or removing Gi Plug 2. Ensure the board is properly seated on the GPIO header and avoid forcing it. Do not exceed the GPIO current limits and keep the board away from liquids or moisture. Handle the device by its edges to minimize static risk.

Gi Plug 2 is hardware oriented, so most software work involves addressing the extra GPIO pins with your preferred GPIO library (for example RPi.GPIO or gpiozero). No special drivers are typically required beyond the standard Raspberry Pi GPIO access libraries.
