Elecrow CrowPanel Advance 2.4 Inch HMI|ESP32-S3 AI-Powered IPS Touch Screen (320x240)|Without Acrylic Case
This Advance ESP32 2.4-inch display is an upgraded version of the CrowPanel HMI display. It is a powerful HMI touchscreen with a 320*240 IPS display. It adopts the ESP32-S3 chip as the core processor, with an Xtensa 32-bit LX7 dual-core processor. It runs at up to 240MHz. It has 512KB SRAM, 8M PSRAM, and 16M Flash. This gives the device strong data processing power.
The integrated 2.4GHz Wi-Fi and BLE functions, combined with the built-in RF antenna, ensure the stability and reliability of the wireless connection. In addition, the diverse interfaces and excellent low power make this 2.4” screen ideal for HMI applications with strict wireless connectivity requirements. It supports the Arduino IDE, Espressif IDF, and PlatformIO. It is compatible with the LVGL graphics library and supports C++.
This 2.4” screen uses an IPS panel. Its 178°viewing angle lets you enjoy a vivid view from any angle. The capacitive touch technology brings you smooth and responsive interactive operations, making every touch accurate and intuitive.
A notable feature of the CrowPanel Advance 2.4-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 its modular design, which provides diversified wireless communication options. Users can replace modules as needed. They support multiple protocols, including 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.
This upgrade enhances connectivity flexibility and reliability, provides more diverse application possibilities, and meets the demands of modern intelligent systems for remote monitoring and control, while also presenting new opportunities for Industry 4.0.
