RAK3312 Dual Core WiFi BLE Espressif ESP32-S3 Module for LoRaWAN® with LoRa SX1262. 800 MHz frequency for EU68/IN865/RU864

The WisBlock Core RAK3312 module for LoRaWAN combines LoRa, WiFi, and Bluetooth communications into a single low-power WisBlock Core module. The device is powered by the Espressif ESP32-S3 dual-core MCU, paired with the Semtech SX1262 LoRa transceiver. The LoRaWAN stack complies with V1.0.2, with V1.0.4 support under development. It controls the Semtech SX1262 LoRa transceiver via its SPI interface. The ESP32-S3 firmware is based on Espressif's Arduino BSP for ESP32. WiFi and Bluetooth functionalities are provided by the Arduino BSP. LoRa drivers and the LoRaWAN V1.0.2 stack are available as an Arduino library.

The RAK3312 comes without predefined firmware. We provide code examples in our WisBlock GitHub repository. Custom firmware for the module, combining the three connectivity options, can be developed with the Arduino IDE and the Espressif ESP32 BSP, or directly using the Espressif ESP-IDF. This module complies with LoRaWAN 1.0.2 Classes A and C specifications. An update to the LoRaWAN V1.0.4 stack is under development and will support Classes A, B, and C.

Integrating the RAK3312 reduces hardware complexity and accelerates the development of IoT solutions, ensuring that systems can adapt to changing communication needs without having to redesign the core electronics.

Why it's useful:

- Design efficiency: Simplifies connectivity integration in IoT devices
- Adaptability: Supports multiple use cases in different environments
- Scalability: Provides a suitable foundation for both prototypes and large-scale deployments

This module supports a wide range of applications, offering practical benefits that go beyond simple connectivity.

- Reduces time from concept to field-ready device
- Encourages flexibility in application design
- Provides a foundation for sustainable product lifecycles
