+      The development board based on the ESP32-S3-Plus XIAO, equipped with the W5500 Ethernet chip, provides wired network connectivity and supports Power over Ethernet (PoE). Please note that after installation via this website, Wi-Fi will be disabled, and the device must be connected via Ethernet.
+    </p>
+    <p>
+      <b>Note:</b> Only V1.2 boards (produced after November 1, 2025) are supported.
+      Earlier versions were never originally intended for use as active Bluetooth proxies
+      and are not compatible due to a missing interrupt pin connection for the W5500
+      Ethernet chip and Bluetooth RF performance issues.
+      See the <a href="https://community.home-assistant.io/t/great-esp32-board-for-an-esphome-bluetooth-proxy/916767/22">forum post</a> for more details and support options for early-batch units.
