RAKwireless RAK4270-EU868 Breakout Board

Rak Wireless' LoRa RAK4270 LoRa® Breakout Module supports eight signal spreading modes (SF5 ~ SF12) and can adjust the bandwidth from 7.8 kHz to 500 kHz. The product features low power consumption (1.5uA in sleep mode), can transmit at 22 dBm and provides a receive sensitivity of -138 dBm.

The RAK4270 LoRa® Breakout Module is compliant with the LoRaWAN® 1.0.2 standard, providing stable long-distance data transfer with low power consumption. The solution will prove its worth in smart metering, agriculture, smart city or logistics tracking applications.

The module can be controlled by AT commands, sent via the UART interface.
