README
README.mdHacker Devices — Open Hardware for Security Research
A collection of fully open-source hardware designs for legitimate security research and pentesting. Every device is complete end-to-end: engineering docs, KiCad schematics & PCB layouts, production C/Python firmware, and React Native companion apps. Build it, flash it, run the app, start researching.
What's Inside Every Device
No half-finished reference designs. Each device folder contains the full stack:
| Category | Files | Description |
|---|---|---|
| Engineering Docs | phase1_conceptual_architecture.md → phase4_software_stack.md | 4-phase design process: requirements, BOM & netlists, PCB layout rules, software stack |
| KiCad Schematics | kicad/*.kicad_pro, *.kicad_sch, *.kicad_pcb | Full schematic with real component symbols, net labels, power flags, and board outline with placed footprints |
| C/Python Firmware | firmware/main.c, registers.h, board.h, drivers/, Makefile | Production-quality MCU firmware — init code, drivers with DMA, USB descriptors, wire protocol |
| React Native App | app/App.js, screens/, components/, utils/protocol.js, package.json | Companion mobile app for device control, configuration, real-time status, and data capture |
Design Methodology
Every device follows a rigorous 4-phase process:
| Phase | Document | Contents |
|---|---|---|
| Phase 1 | phase1_conceptual_architecture.md | Purpose, performance targets, constraints, block diagram, bus topology, power domains |
| Phase 2 | phase2_component_selection_schematics.md | BOM with real part numbers, pinouts/MUX tables, decoupling networks, netlists, impedance matching |
| Phase 3 | phase3_pcb_blueprints_layout.md | PCB stackup, routing rules, length matching, via strategy, thermal management, DFM notes |
| Phase 4 | phase4_software_stack.md | MMIO/register defs, clock & GPIO init (production C), critical device driver, device tree, bootloader |

Constraints
- BOM target: Under $100 per device
- Form factor: Portable, USB-powered or battery-operated
- All designs use real, purchasable components with exact part numbers
- KiCad schematics are valid KiCad 7+ format — open them directly
- Firmware is production-quality C — not stubs or pseudocode
- React Native apps have working UI with proper state management and wire protocol matching the firmware

Questions
How big is the Device PCB?
It measures 22 × 18 mm and has 4 copper layers, 0.4 mm thick.
What parts does the Device use?
18 parts, built around the ICE40UP5K-SG48I, ESP32-S3-MINI-1-N8, NRF52840-QIAA-R7 and W25Q128JVSIQ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Device KiCad files?
From the jayis1/hacker-devices repository on GitHub, at the commit this page was made from: the board is glyph-reaper/kicad/device.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Device design in my own project?
Its repository states no licence, so its author keeps all rights: ask jayis1 before reusing the design.
