RAKwireless RAK4631-EU868-RUI

The RAK4631-R WisBlock Core module is a RAK4630 stamp module with an expansion PCB and connectors compatible with WisBlock Base. It allows an easy way to access the pins of the RAK4630 module to simplify development and testing processes.

The module itself comprises a RAK4630 as its main component. The RAK4630 is a combination of an nRF52840 MCU and an SX1262 LoRa chip. It features ultra-low power consumption of 2.0 uA during sleep mode, high LoRa output power up to 22 dBm during a transmission mode, and the BLE interface with output power up to 4 dBm.

Also, it complies with LoRaWAN 1.0.3 protocols and supports LoRa point-to-point communication. The RF communication characteristic of the module (LoRa + BLE) makes it suitable for a variety of applications in the IoT field, such as home automation, sensor networks, building automation, personal area networks applications (health/fitness sensors, and monitors, etc.).
