Elecrow CrowPanel Advance 3.5inch -HMI ESP32 AI Display for Meshtastic 480x320 Artificial Intelligent IPS Touch Screen-Without Case

This Advance ESP32 3.5-inch display is the Meshtastic version of the CrowPanel Advanced display. The included SX1262 LoRa module allows the screen to access the Meshtastic network and talk to other Meshtastic devices.

It is a powerful HMI touch display with a 480*320 resolution IPS screen. It uses the ESP32-S3 chip as the core processor. This chip is equipped with an Xtensa 32-bit LX7 dual-core processor with a main frequency of up to 240MHz, equipped with 512KB SRAM, 8M PSRAM and 16M Flash, providing the device with powerful data processing capabilities. 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. Also, the diverse interfaces and low power make this 3.5-inch 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 3.5-inch 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 3.5-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. With the SX1262 wireless module, the Advance 3.5" HMI display can support access to the Meshtastic network(An open source, off-grid, decentralized, mesh network built to run on affordable, low-power devices). 

This display integrates the latest Meshtastic technology, optimized port layout, excellent display touch performance, and larger storage space. 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. This 3.5" display also supports tactility. Click here to learn more.
