Low power LoRaWAN Module Series

25/08/2023

Delivering exceptional range with minimal power consumption for challenging RF use cases

Based on a Silicon Labs SoC and the Semtech SX126x radio, the RM126x directly targets OEM customers that require exceptional long range, yet minimal power consumption. The RM126x module series comes as two variants with the RM1262 based on the SX1262 chipset and the RM1261 based on the SX1261 chipset.

These small form factor PCB modules are the smallest LoRaWAN modules on the market with a built in MHF4 connector. The integrated TCXO ensures superior performance across the entire industrial temperature range (-40 to +85 °C) and the on-board DC-DC converter provides ultra-low power consumption. Together these features enable customers to accelerate their time to market and integrate into compact product form factors.

The RM126x series has been developed with sub-GHz antennas available in the popular FlexPIFA and i-FlexPIFA series’. Solutions are available for both 868 & 915MHz frequency bands. The module/antenna combinations are certified to work all over the world including:

RM1261 – Europe, UK, Taiwan, Japan, India
RM1262 – USA, Canada, Australia, New Zealand

Main Features

Based on Silicon Labs EFR32/Semtech SX126X

Our first module based on the Silicon Labs EFR32 series and Semtech SX126x radio, enabling development with Silicon Labs tools.

Ultra-low power consumption

By messaging infrequently, devices can last for over a year of use on a single battery without charging or replacement.

LoRa P2P communication

Peer-to-peer architecture allows nodes to communicate with other nodes, creating a self-contained network without a traditional gateway.

Develop your way-hosted and hostless options

Fully-featured and extensible AT command set makes it easy to write wireless applications in a familiar format and use Silicon Labs Simplicity Studio to write your own application using C, utilizing radio certifications.

Broad regulatory support

Support for USA, Canada, Australia, and New Zealand (RM1262) as well as Europe, UK, Taiwan, Japan, and India (RM1261).

Personal support from design to manufacture

Our industry-renowned support is passionate about helping you speed your design to market.
