RAK3112 WisDuo LoRa + WiFi + BLE module targets Edge AI and Meshtastic UI

RAKwireless “RAK3112 WisDuo Module for Edge AI with LoRa” combines an ESP32-S3 WiFi and BLE SoC with a Semtech SX1262 LoRa transceiver for Edge AI applications and Meshtastic user interfaces. The 3-in-1 LoRa + WiFi + BLE module is an update to the ESP32-based RAK11200 WisDuo LoRa module, which has limitations in terms of computing power and memory. Those became apparent in more demanding applications such as Edge AI or complex mesh networks. With 16MB of flash and 8MB of PSRAM and a more powerful ESP32-S3 microcontroller, the RAK3112 WisDuo module overcomes those limitations for camera and audio processing, as well as mesh networks like Meshtastic. It also offers a more powerful alternative to the pin-compatible RAK11160 STM32 + ESP32-C2 module that’s better suited for battery-powered sensors.
