+================
+ESP32S3-8048S043
+================
+
+.. tags:: chip:esp32, chip:esp32s3
+
+The `ESP32S3-8048S343 
<https://www.openhasp.com/0.7.0/hardware/sunton/esp32-8048s0xx/>` is a 
dual-core MCU, integrated WI-FI and Bluetooth functions, the main frequency can 
reach 240MHz, 512KB SRAM, 384KB ROM, 8M PSRAM, Flash size is 16MB.
+
+.. list-table::
+   :align: center
+
+   * - .. figure:: esp32s3-8048S043.png
+          :align: center
+
+Features
+========
+
+  - ESP32-S3 WROOM-1 Module
+  - USB Type-C ports
+  - Power LED
+  - LCD Display
+  - 8MB Octal PSRAM
+  - 16MB SPI Flash
+  - TF card slot
+  - RST and BOOT buttons (BOOT accessible to user)
+
+Serial Console
+==============
+
+UART0 is, by default, the serial console.  It connects to the on-board
+CP2102 converter and is available on the USB connector USB CON8 (J1).
+
+It will show up as /dev/ttyUSB[n] where [n] will probably be 0.
+
+Buttons and I/Os
+================
+
+The board has two buttons: Boot and EN. The EN button functions only as 
+reset and is not available to software. The BOOT button (connected to IO0)
+determines boot mode during reset and can be used as software input after
+initialization. Most I/O pins are available on the back of the board through 
+two JST 1.28mm 4P connectors.
+
+Configurations
+==============
+
+All of the configurations presented below can be tested by running the 
following commands::
+
+    $ ./tools/configure.sh esp32s3-8048S043:<config_name>
+    $ make flash ESPTOOL_PORT=/dev/ttyUSB0 -j
+
+Where <config_name> is the name of board configuration you want to use, i.e.: 
nsh, buttons, tc...
+Then use a serial console terminal like ``picocom`` configured to 115200 8N1.
+
+buttons
+-------
+
+This configuration shows the use of the buttons subsystem. It can be used by 
executing
+the ``buttons`` application and pressing on any of the available board 
buttons::
+
+    nsh> buttons
+    buttons_main: Starting the button_daemon
+    buttons_main: button_daemon started
+    button_daemon: Running
+    button_daemon: Opening /dev/buttons
+    button_daemon: Supported BUTTONs 0x01
+    nsh> Sample = 1
+    Sample = 0
+
+nsh
+---
+
+Basic NuttShell configuration (console enabled in UART0, exposed via
+USB connection by means of CP2102 converter, at 115200 bps).
+
+i2c
+------
+
+This configuration can be used to scan and manipulate I2C devices.
+You can scan for all I2C devices using the following command::
+
+    nsh> i2c dev 0x00 0x7f
+
+touchscreen
+------------
+
+The LCD panel comes with the integrated capacitive touchscreen sensor 
+GT911 connected to the pins 20 (SCL), 19 (SDA) and address 0x5D::
+
+    nsh> tc
+    tc_main: nsamples: 0
+    tc_main: Opening /dev/input0
+    Sample     :
+       npoints : 1
+    Point 1    :
+            id : 0
+         flags : 31
+             x : 149
+             y : 140
+             h : 0
+             w : 0
+      pressure : 45

+ *         implementation without modification.  The argument has no
+ *         meaning to NuttX; the meaning of the argument is a contract
+ *         between the board-specific initialization logic and the
+ *         matching application logic.  The value could be such things as a
+ *         mode enumeration value, a set of DIP switch settings, a
+ *         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.
+ *
+ * Returned Value:
+ *   Zero (OK) is returned on success; a negated errno value is returned on
+ *   any failure to indicate the nature of the failure.

+ * Returned Value:

+ *   board due to some constraints.  The return value in this case is a
+ *   board-specific reason for the failure to shutdown.
