Supports multiple IDEs for easy integration and development: The RAK4631 can be easily programmed through the for IDE or other IDE extensions. It also has a version RAK4631-R configured with the low-code development platform RUI3, which allows users to develop customized firmware via RUIAPI and also send AT commands via USB, UART or Bluetooth. Multiple Connection Methods, Multiple Scenario Applications: With communication features such as LoRa and Bluetooth, the RAK4631 module is suitable for a variety of applications in the IoT field, such as smart home, building automation, and personal health monitoring. LoRa point-to-point communication with low power consumption and high transmission efficiency: The module is compliant with LoRaWAN1.0.2 protocol and supports LoRa point-to-point communication. In sleep mode, power consumption is as low as 2.0 ; in transmission mode, LoRa output power is up to 22 dBm, and Bluetooth output power is up to 4 dBm, making it a cost-effective communication solution.
