+ ESP32-S3-LCD-EV is an ESP32-S3-based development board with a
touchscreen.
+ Together with different subboards, ESP32-S3-LCD-EV-Board can
drive LCDs with IIC,
+ SPI, 8080, and RGB interfaces.
+ It houses dual array microphones, supports voice recognition
and near/far-field
+ voice wake-up, and features screen and voice interaction.
+ The board caters to development needs for touchscreen products
with different resolutions
+ and interfaces. Currently, we have two boards available:
+
+ 1. ESP32-S3-LCD-EV-Board with 480x480 LCD
+ 2. ESP32-S3-LCD-EV-Board with 800x480 LCD

+ * pointer to configuration data read from a file or serial FLASH,
+ * or whatever you would like to do with it. Every implementation
+ * should accept zero/NULL as a default configuration.
