Overview: The Proxmark3 Easy V3.0 is an essential, portable RFID research tool built for both field work and lab analysis. It supports a wide range of RFID standards (125 kHz EM, 13.56 MHz ISO14443A/B, ISO15693, and more) and exposes low-level frames for deep inspection.

Key Specs: USB-powered, Open-source firmware, supports sniffing, cloning, emulation, and tag dumping. Community tools available for Windows, Linux, and macOS.

Why it's useful: For penetration testers and hardware security researchers, Proxmark3 lets you capture raw modulated signals, analyze tag responses, and test access control implementations. It's the go-to when you need full protocol visibility beyond consumer NFC apps.

Practical notes & workflow: Expect a learning curve — working with Proxmark requires familiarity with command-line workflows and RFID protocol concepts.

Pros: deep protocol access, strong community, regularly updated tools.

Cons: isn’t plug-and-play for beginners (requires CLI), hardware clones vary in quality, and regulatory considerations apply to some locales.

Overview: AI-capable microcontroller with built-in camera, Wi-Fi, BLE 5.0, and onboard sensors for IoT security builds.

Use cases: perimeter monitoring, badge prototypes, smart sensors, automation triggers.

Overview: The Flipper Zero Devboard adds Wi-Fi and expanded RF capabilities to the popular Flipper Zero ecosystem—turning a pocket toy into a versatile analysis tool for sub-GHz, RFID, Bluetooth, and now Wi-Fi assisted tasks.

Key Specs: Compact devboard form factor, integrates with the Flipper firmware, supports custom payloads, and can extend the Flipper with network-based features like remote control and OTA payloads.

Why it's useful: When paired with the Flipper firmware and scripts, the devboard allows testers to prototype Wi-Fi-adjacent attacks, automate routines, and capture simple network metadata in portable ops.

Pros/Cons: Great for demos; not a full Wi-Fi auditing platform.

Overview: Compact rogue AP/MITM testing platform with modules and web UI.

Notes: Use in isolated/lab networks with written authorization.

Overview: USB-Ethernet adapter with embedded Linux for persistence/pivoting during authorized engagements.

Reliable monitor mode + injection; mind driver versions for your distro.

Wide RF coverage for reconnaissance/decoding common protocols; great low-cost SDR.

Blocks data lines to prevent juice-jacking; prefer PD-compatible units.

RF isolation for evidence/travel privacy; verify attenuation with a quick call test.

Inline packet capture without impacting traffic; choose correct media/speed.

Quickly power APs/cameras; match 802.3af/at and label power budgets.

Portable lab host/DNS sinkhole/mini-VM box; mind thermals and storage I/O.

Fast portable storage for PCAPs/VMs; use encryption and checksums.

Run devboards/laptops in the field; confirm real-world PD output/passthrough.

Clean terminations for keystones/patch panels; keep spare blades.

Measure voltage/current/power on PD lines; useful for debugging power flakiness.
