GhostHID Turns a Tiny USB Stick into a Network Keyboard

Field notes

GhostHID presents an ESP32-S3 board as a standard USB keyboard and mouse while accepting input through a web interface served from the device. Its feature set extends beyond typing: the page describes desktop screen-edge layouts, presenter timers, lock-key loopback confirmation, media and power keys, and up to four simultaneous controllers. A browser Web Serial flasher, roughly 1.3 MB firmware image, OTA support, and a printable three-part case indicate a project designed for hands-on deployment rather than a purely conceptual demo.
