ESP32 WROOM WiFi Bluetooth Development Board with 2.8" LCD TFT Touch Screen 240×320 | IoT HMI Smart Display

ESP32 WROOM WiFi & Bluetooth Development Board — 2.8" LCD TFT Touch Screen 240×320

A powerful all-in-one development platform combining the ESP32-WROOM dual-core WiFi and Bluetooth module with a 2.8" 240×320 ILI9341 LCD TFT touch screen — giving you a complete IoT display and control system on a single board. The ESP32’s dual-core 240MHz processor handles both the wireless communication stack and the display rendering simultaneously, making it ideal for smart home dashboards, IoT sensor displays, HMI (human-machine interface) panels, and interactive embedded projects. Available with or without a protective case.

Arduino Quick Start

1. Install the ESP32 board package in Arduino IDE via Boards Manager (search “ESP32” by Espressif).
2. Install the TFT_eSPI library via Library Manager. Configure User_Setup.h for ILI9341 + XPT2046.
3. Select the correct ESP32 board and COM port.
4. Upload the TFT_eSPI graphicstest example to verify the display.
5. Build your UI using TFT_eSPI, LVGL, or custom graphics code.

Frequently Asked Questions

Q: Which display library should I use?
A: TFT_eSPI is the most popular and well-supported library for ILI9341 displays on ESP32. LVGL (Light and Versatile Graphics Library) is recommended for complex UI with buttons, sliders, and animations.

Q: Does the touch screen work with TFT_eSPI?
A: Yes. TFT_eSPI includes XPT2046 touch support. Calibrate the touch screen using the TFT_eSPI touch calibration example before use.

Q: Can I connect external sensors to this board?
A: Yes. The ESP32 GPIO pins are accessible on the board headers. Connect I2C sensors (SDA/SCL), SPI devices, UART modules, and analogue sensors to the available GPIO pins.
