This core module brings LoRa, Wi-Fi and Bluetooth together on one small board for the modular IoT system. A dual-core ESP32-S3 processor with plenty of memory runs the application, and a Semtech SX1262 radio handles long-range LoRa.
With Wi-Fi on board it can act as a LoRa-to-Wi-Fi bridge or MQTT gateway, and its larger memory suits graphic displays, Meshtastic user interfaces and light edge AI.
