+ESP32-2432S028
+==============
+
+The ESP32-2432S028 is a development board based on an ESP32-WROVER-32 module.
It is designed for a
+wide range of applications, particularly in the field of the Internet of
Things (IoT).

+
+ ESP32-2432S028 board layout - back
+
+Features
+========
+
+ - LCD screen (2.8 inch)
+ - MicroSD card slot
+ - RGB LED
+ - Audio
+ - Light Dependent Resistor (LDR)
+
+Most of I/O pins are broken out to the boards, but from the back side of the
board, there are
+some pins available are separated into two connectors femme JST 1.28 mm 4P.
+
+Serial Console
+==============
+
+UART0 is, by default, the serial console. It connects to the on-board
+CH340 converter.
+
+Buttons and LEDs
+================
+
+Board Buttons
+-------------
+
+There are two buttons labeled BOOT and RST. The RST button is not available
+to software. It pulls the chip enable line that doubles as a reset line.
+
+The BOOT button is connected to IO0. On reset it is used as a strapping
+pin to determine whether the chip boots normally or into the serial
+bootloader. After reset, however, the BOOT button can be used for software
+input.
+
+Board LEDs
+----------
+
+There is one RGB LED available.

+26 Audio Out
+34 LDR
+===== ========================= ==========
+
+Configurations
+==============
+
+All of the configurations presented below can be tested by running the
following commands::
+
+ $ ./tools/configure.sh esp32-2432S028:<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, wifi...
+Then use a serial console terminal like ``picocom`` configured to 115200 8N1.
+
+lvgl
+----
+
+This is a demonstration of the LVGL graphics library running on the NuttX LCD
+driver. You can find LVGL here::
+
+ https://www.lvgl.io/
+ https://github.com/lvgl/lvgl
+
+This configuration uses the LVGL demonstration at `apps/examples/lvgldemo`.
+
+nsh
+---
+
+Basic NuttShell configuration (console enabled in UART0, exposed via
+USB connection by means of CH340 converter, at 115200 bps).

+ * or whatever you would like to do with it. Every implementation
+ * should accept zero/NULL as a default configuration.
