/*
 * ESP-WROOM-32 U.FL Board Interface Implementation
 *
 * This board is a generic ESP-WROOM-32 dev board with external U.FL antenna.
 * It has no built-in display, so it defaults to WebUI mode for interaction.
 *
 * Features:
 * - No built-in screen (uses WebUI)
 * - No built-in battery
 * - Boot button on GPIO0 for input
 * - LED on GPIO2
