 However, ESP modules equipped with the ESP32-S3 chip have native USB support and can potentially communicate using UART protocol if the USB Type-A connector is directly connected to the ESP pins without an intermediary chip. This setup allows for creating an ESPHome configuration that utilizes the same pins for UART communication.
 
-Currently, the `M5Stack AtomS3U <https://shop.m5stack.com/products/atoms3u>`_ and `Lilygo T-Dongle S3 <https://www.lilygo.cc/products/t-dongle-s3?variant=42455191519413>`_ confirmed board that supports this configuration, though there may be others.

 - **Configuration Issues:** There might be issues with your ESPHome configuration.
 - **Hardware Problems:** The problem could lie with the ESP module or other hardware components.
-- **Wiring Issues:** Incorrect wiring or problems with the pins could be causing communication failures.
+- **Wiring Issues:** Incorrect wiring or problems with the pins could be causing communication failures. Most common mistake is to swap RX and TX pins.
 - **Protocol Mismatch:** The AC might use a different protocol for communication or may not support serial communication at all.
