 ### Hardware Required
 
 * A development board with any supported Espressif SOC chip (see `Supported Targets` table above)
+    * The example can be preconfigured for [ESP-BOX](https://components.espressif.com/components/espressif/esp-box), [ESP32-S2-Kaluga-kit](https://components.espressif.com/components/espressif/esp32_s2_kaluga_kit) and [ESP32-S3-LCD-EV-board](https://components.espressif.com/components/espressif/esp32_s3_lcd_ev_board). More information is in 'Configure the Project' section.
 * A USB cable for power supply and programming.
 * A board with ES8311 codec, mic and earphone interface(e.g. ESP-LyraT-8311A extension board).
