ESP32 2.8-Inch Smart Display Development Board with Resistive Touch

This development board pairs a high-performance ESP32 microcontroller with a 2.8-inch colour TFT display and resistive touch screen. Featuring built-in Wi-Fi, Bluetooth, and compatibility with the Arduino LVGL graphics library, it is an all-in-one solution for interactive IoT projects. It is well-suited to students, hobbyists, and makers building touch-driven user interfaces and connected controllers.

Interactive colour touch screen

The board is equipped with a 2.8-inch 240 x 320 colour TFT display and resistive touch interface. It supports the Arduino LVGL library, allowing developers to generate and run high-quality graphical user interfaces with ease.

Dual-core processing and wireless support

Powered by a low-power dual-core 32-bit CPU running at up to 240 MHz (600 DMIPS), the board is programmable via the Arduino IDE. It features an onboard antenna offering 802.11b/g/n/e/i Wi-Fi and dual-mode Bluetooth 4.2 BR/EDR and BLE.

Memory and expansion capability

Onboard storage includes 520 KB internal SRAM, 32 Mbit default SPI Flash, and a TF card slot supporting up to 16 GB. An IO expansion port provides access to GPIO pins supporting UART, I2C, and PWM communication protocols up to 2 Mbps.

Power efficiency and specifications

The board operates on a 4.75V to 5.25V supply, drawing 180mA with the flash off, 310mA at maximum screen brightness, and as low as 6mA in deep sleep mode. It functions across an operating temperature range of -20 ℃ to 70 ℃.
