The CrowPanel Advance 3.5" HMI ESP32 AI Display for Meshtastic is an upgraded intelligent display from the CrowPanel Advance Series, designed to deliver enhanced performance, rich features, and seamless connectivity.
This Meshtastic-enabled version integrates the SX1262 LoRa module, allowing the display to connect directly to the Meshtastic mesh network and communicate with other devices in off-grid environments.
Powered by the ESP32-S3 processor, featuring a dual-core Xtensa LX7 CPU running up to 240MHz, along with 512KB SRAM, 8MB PSRAM, and 16MB Flash, the device provides powerful processing for complex applications. It also includes Wi-Fi and Bluetooth connectivity, ensuring reliable wireless communication.
The 3.5-inch IPS display (480×320 resolution) offers a wide 178° viewing angle and responsive capacitive touch, delivering an intuitive and immersive user experience.
A standout feature is its integrated AI functionality, supporting voice recognition and speech synthesis through a built-in microphone and speaker, enabling natural interaction with smart assistants.
With support for Arduino IDE, Espressif IDF, PlatformIO, and compatibility with the LVGL graphics library, developers can easily build custom UI applications. Combined with flexible wireless module support and extensive I/O, this display is ideal for modern IoT, HMI, and embedded systems.
