Elecrow CrowPanel Advance 2.8 Inch HMI|ESP32-S3 AI-Powered IPS Touch Screen (320x240)|Without Acrylic Case
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, and PlatformIO. It is compatible with the LVGL graphics library and supports 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-inch 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 that its modular design provides diversified wireless communication options. Users can replace modules as needed. They support multiple protocols: Zigbee, LoRa, nRF2401, Matter, Thread, Wi-Fi HaLow, and Wi-Fi 6. In addition, when paired with the SX1262 wireless module, it can support access to the Meshtastic network(An open source, off-grid, decentralized, mesh network built to run on affordable, low-power devices). One screen and different modules can meet the wireless connection needs of different scenarios
