The CrowPanel Advance 3.5" is a Meshtastic-ready HMI touchscreen display powered by an ESP32-S3 with an onboard SX1262 LoRa module. It features a 480 × 320 IPS capacitive touch panel, integrated AI voice interaction via microphone and speaker, and a replaceable wireless module design for flexible connectivity options.

Pre-loaded with the Meshtastic firmware, this display connects to the open-source, off-grid mesh network out of the box. It supports development via Arduino IDE, ESP-IDF, PlatformIO, and the LVGL graphics library.
