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 75 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Device use?
4 parts, built around the STM32G474VET6, ADS8684IDBTR and 74LVC14AD. 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 sent-sentinel/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.
