NetWraith is an open-source, modular hardware multi-tool powered by the ESP32-C5, designed as a direct Android companion device via USB-C. It turns an Android smartphone into a portable RF, RFID/NFC, and infrared analysis suite powered directly by the phone's battery over USB-OTG, now featuring Dual-Band Wi-Fi (2.4/5GHz) and a Quad-Antenna Array for extreme range.

Features
- Microcontroller: ESP32-C5-WROOM-1U (Dual-band 2.4/5GHz Wi-Fi + Bluetooth LE 5) with native USB-OTG support.
- Quad-Antenna Array: 4 dedicated external antennas via SMA and U.FL connectors for maximum signal capture and injection range.
- Sub-GHz Transceiver: CC1101 (300–928 MHz, default 433 MHz) for IoT and remote automation capture/replay.
- 2.4 GHz Auditing: NRF24L01+ for wireless protocol analysis and packet monitoring.
- Dual-Band Proximity:
- 13.56 MHz (HF): PN532 V3 module supporting NFC Forum tags, MIFARE, and FeliCa.
- 125 kHz (LF): RDM6300 receiver with external wire terminal coil antenna for EM4100/TK4100 ID badges.
- Infrared Transceiver: 38 kHz modulated VS1838B receiver and 940 nm high-power emitter for learning and blasting IR codes.
- Local Storage: MicroSD SPI card slot for raw signal dumps and offline payloads.
- Host Connectivity: 16-pin USB-C receptacle configured with dual 5.1kΩ pull-down resistors for native Android USB host recognition and wired data transfer.

Questions
What parts does the NetWraith use?
15 parts, built around the CC1101RGP and ESP32-C5-WROOM-1U-N8R8. 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 NetWraith KiCad files?
From the Chronos-03/NetWraith repository on GitHub, at the commit this page was made from: the board is PCB/Untitled.kicad_pcb and its schematic PCB/Untitled.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NetWraith design in my own project?
Its repository states no licence, so its author keeps all rights: ask Chronos-03 before reusing the design.
