CrowPanel Advance 2.8''-HMI ESP32 AI Functions Display 320x240 IPS Touch Screen Support Arduino/LVGL/Micropython

The Advance ESP32 2.8-inch AI display is an upgraded version of the CrowPanel HMI 2.8-inch display. It is a powerful HMI touch display feature with a 320*240 resolution IPS screen. It uses the ESP32-S3 chip as the core processor, equipped with an Xtensa 32-bit LX7 dual-core processor and a main frequency of up to 240MHz. It has 512KB SRAM, 8M PSRAM, and 16M Flash. This gives it strong data processing power. The 2.4GHz Wi-Fi and BLE functions, with a built-in RF antenna, ensure a stable, reliable wireless connection. Also, the diverse interfaces and low power make this 2.8” screen ideal for HMI applications that need strong wireless connectivity. It supports the Arduino IDE, Espressif IDF, PlatformIO and MicroPython. It is compatible with the LVGL graphics library and supports MicroPython and C++.

This 2.8” screen uses an IPS panel, and the 178°wide viewing angle allows you to enjoy a vivid visual experience at any angle. Capacitive touch technology enables smooth, responsive interactions. It makes every touch accurate and intuitive.

A notable feature of the CrowPanel Advance 2.8” display is its integrated AI function. Users can interact by using the microphone and speaker. This includes voice recognition and speech synthesis. They can have seamless conversations with smart assistants to get information.

Another highlight of this screen is its modular design. It provides diverse wireless options. Users can replace modules as needed. They support multiple protocols: Zigbee, LoRa, nRF2401, Matter, Thread, and Wi-Fi 6. In addition, when paired with the SX1262 wireless module, One screen and different modules can connect wirelessly in any scenario.

This upgrade integrates the latest wireless tech, an optimized port layout, a great touch display, and larger storage. These improvements enhance the flexibility and reliability of connectivity, provide users with more diverse choices and wider application possibilities, and meet the stringent requirements of modern intelligent systems for remote monitoring and control.
