## What it is
HaleHound-CYD is a multi-protocol offensive security toolkit firmware for the ESP32 Cheap Yellow Display, offering 40+ attack modules across WiFi, Bluetooth, SubGHz, 2.4GHz, and NFC. It runs entirely on the touchscreen device with optional external radio modules like CC1101, NRF24L01+, PN532, and GPS.

## Use cases
- flash a pentest toolkit onto a cheap yellow display esp32
- scan and attack wifi networks from a handheld device
- test bluetooth and subghz security on the go
- run nfc and 2.4ghz attacks with a CYD board
- build a portable offensive security device for under $10
- explore radio hacking with cc1101 and nrf24l01 modules

## When to choose
- you own a Cheap Yellow Display or compatible ESP32 board and want a ready-made offensive security toolkit
- you want a touch-driven, no-computer-needed device for wifi, bluetooth, subghz, or NFC testing
- you want browser-based flashing without installing toolchains

## When to avoid
- you need a defensive or compliance-focused security scanner rather than offensive tooling
- you require legal guarantees or licensed firmware (license is non-standard)
- you need support for boards other than the listed ESP32 CYD variants
