     The ESP32-2432S028R is a ready development board that combines a 2.8 inch 240x320 pixel color TFT display and a resistive touch panel with the ESP32-WROOM-32 module on the same board. The ESP32-WROOM-32 is a dual core processor running up to 240MHz with WiFi and Bluetooth support; it has 520KB SRAM, 448KB ROM and 4MB flash memory. The display works with the ILI9341 driver and the touch panel with the XPT2046 controller; a touch device that controls, senses, monitors and logs over WiFi is built without a separate display, cables or soldering.

     The board carries a Micro SD card slot, a 2-pin speaker output, an RGB LED on the back, an LDR light sensor on the front, a CH340 USB-serial converter, and BOOT and RESET buttons. Temperature-humidity sensors and similar modules are connected via the serial port (P1) and the free GPIO / I2C connectors (P3, CN1); the display backlight is adjusted by software. The board is powered by 5V USB, fixed into an enclosure with 4 mounting holes and comes with a demo program installed.

     It is programmed with Arduino IDE, ESP-IDF, MicroPython, Scratch and Mixly. In jobs such as a home automation panel, thermostat, weather station, WiFi clock, energy monitoring and alarm display, it offers a one-piece solution because the same board handles both the display and the wireless connection.

Key features:

     Display and processor on one board: The 2.8 inch 240x320 TFT display, touch panel and ESP32-WROOM-32 are on the same PCB; the display connection is ready, there are no cables and no soldering.

     WiFi and Bluetooth: With the dual core 240MHz ESP32 the display can receive data from the internet, an MQTT server or a phone, and send commands given by touch wirelessly.

     Touch control: Thanks to the resistive panel and XPT2046 controller, buttons, menus and sliders are used directly on the screen. A stylus is included.

     Ready peripherals: Micro SD slot, speaker output, RGB LED and LDR light sensor are on the board; no extra module is needed for logging, audible alerts, a status light and brightness adjustment by ambient light.

     USB programming: Thanks to the CH340 USB-serial converter and the BOOT / RESET buttons, the board is both powered and programmed with a single USB cable.

Usage information:

• Connect the board to the computer with the supplied USB cable. If the computer does not recognize the board, install the CH340 driver (CH341SER): wch-ic.com/products/CH340.html
• In Arduino IDE install the ESP32 board package and select ESP32 Dev Module. If uploading does not start, hold the BOOT button and restart the upload.
• The display works with the ILI9341 driver and the touch with the XPT2046 driver; set the pin configuration of the display library according to the board schematic. Example programs and schematic: pan.jczn1688.com/1/ESP32%20module
• Connect the speaker to the P4 connector and sensors to the CN1 (IO22, IO27, 3.3V, GND) or P3 connector with the supplied 4-pin cable. The P1 serial port (TX, RX) is shared with USB, leave it free while uploading; IO21 on P3 drives the display backlight, do not use it for other jobs.

Areas of use:

•  Home automation control and information panel
•  Thermostat and temperature-humidity display
•  Weather station and weather forecast display
•  Clock, calendar and reminder display (time sync over WiFi)
•  Energy consumption and meter monitoring panel
•  Greenhouse and incubator temperature-humidity monitoring
•  Alarm, door and security notification panel
•  Game and touch learning applications
•  Graph and SD card logging of sensor data

Precautions:

•  The touch panel is resistive; it is used by pressing lightly with a stylus or fingertip and does not support multi-touch.
•  The display, touch and SD card use most of the pins; only IO22, IO27 and IO35 (input only) remain free. It is not suitable for jobs that need many relays or sensors.
•  GPIO pins work at 3.3V and are not 5V tolerant; do not connect a sensor with 5V output directly.
•  WiFi and full brightness backlight together draw current; if the board restarts on a computer USB port, power it with a 5V adapter.
