Hardware

This section documents the hardware design of the Lichee-Jack project. All designs are open-source, reproducible, and intended for makers, researchers, and security professionals who want to build or modify the device themselves.

You can explore the hardware in the following categories:

PCB & FPC

Mainboard schematics, PCB layout, FPC designs, power domains, signal routing notes, and manufacturing considerations.

PCB & FPC

3D Print Cases

3D printable enclosure designs, STL sources, print settings, material recommendations, and assembly instructions.

3D PRINT CASES

Extension modules

Expansion and external modules, including GPIO, USB gadgets, sensors, LEDs, audio, and future add-on boards.

EXT MODULES

Design Philosophy

Open-source hardware (OSHW) – all design files are provided
Modular – core board + extension modules
Hackable by design – exposed test pads, headers, and debug interfaces
Linux-first – optimized for embedded Linux workflows

Toolchains & Formats

PCB: KiCad
Mechanical: STEP / STL
Manufacturing: Gerber, drill, pick-and-place

Note

Hardware revisions may change over time. Always check the revision tag that matches your board before manufacturing or assembling.

If you are new to the project, it is recommended to start with PCB & FPC to understand the system architecture, then move on to the 3D printed case and extension modules.
