Product Description
Technical Details
The RAK4631 is a WisBlock core module designed for developers building long-range, low-power LoRa devices that also need BLE for local configuration and commissioning. It combines a Nordic nRF52840 MCU with a Semtech SX1262 LoRa transceiver, supporting both LoRaWAN 1.0.2 and LoRa point-to-point communication.
A major real-world use case is Meshtastic, where the RAK4631 is often selected as a compact LoRa mesh node for off-grid communication, telemetry, and field deployments focused on range and battery life. Beyond Meshtastic, it’s a strong foundation for distributed sensor networks, building automation, and remote monitoring systems running on battery and/or solar power.
With compatibility to the RAK5005-O baseboard, it simplifies prototyping and integration testing by providing easy access to key interfaces. Note: RAK4631 and RAK4631-R share identical hardware, but differ in firmware (Arduino BSP vs. RUI V3).
