RAK5146-225

Overview

The RAK5146-225 is an LPWAN concentrator module based on the Semtech SX1303 LoRa core, designed for LoRaWAN gateway applications. It operates at a frequency of 868MHz and supports both SPI and USB interfaces. The module features integrated GPS capabilities and implements Listen Before Talk (LBT) functionality using the SX126X component. It utilizes a mini-PCIe form factor and requires a 3.3V supply voltage.

Feature Summary

• Integrates Semtech SX1303 LoRa core with SX126X for Listen Before Talk capability
• Supports dual interface connectivity via SPI and USB protocols
• Includes built-in GPS functionality for precise location tracking
• Compact mini-PCIe form factor suitable for size-constrained embedded systems

Applications

• LoRaWAN gateway integration in smart metering fixed networks
• Internet-of-Things (IoT) application deployments
• Embedded platforms requiring compact LPWAN concentrator solutions

Procurement Notes

Verify that the specific suffix -225 corresponds to the 868MHz frequency band required for your regional regulatory compliance. Confirm interface requirements match either SPI or USB support as documented. Ensure host platform provides necessary 3.3V power supply and physical mini-PCIe slot compatibility before procurement.

Selection Notes

Select this module when integrating LoRaWAN gateways into systems with strict mass and size constraints. Choose the RAK5146-225 variant specifically for 868MHz operation regions. Consider the integrated GPS and LBT features if location accuracy and spectrum efficiency are critical design requirements for the target IoT deployment.
