The Advance 3.5-inch Display is a significant upgrade in our HMI lineup.  It combines a vibrant 480*320 IPS touch screen with the powerful ESP32-S3 chip, which features a dual-core Xtensa LX7 processor running at up to 240MHz. With 512KB SRAM, 8MB PSRAM, and 16MB Flash, this display offers robust data processing capabilities, ideal for complex interactive interfaces.

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 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. 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.

This upgrade integrates the latest wireless tech, an optimized port layout, a great touch display, and larger storage. These improvements make connectivity more flexible and reliable. They provide users with a wider range of options and applications, capable of meeting the rigorous demands of modern intelligent remote monitoring and control systems, while also presenting new opportunities for Industry 4.0. This 3.5" display also supports tactility. 

Note: The LoRa module purchased on this page does not include the Meshtastic firmware and is intended solely for LoRa communication. If you want to purchase a screen that supports Meshtastic devices, please click here.
