LoRaWAN modules for challenging global RF applications

Mouser now stocks the RM126x Series LoRaWAN modules from Laird Connectivity. The modules are based on the Silicon Labs EFR32 SoC and Semtech’s SX126x transceivers, with module/antenna combinations certified to work all over the world in either hosted or host-less modes, supplying a global, low-power, long-range solution for challenging LoRaWAN implementations in industrial automation and control, smart agriculture, smart cities, utilities monitoring, transportation, logistics, supply chain, healthcare monitoring, and retail.

The modules directly target OEM customers needing outstanding long-range RF performance and minimal power consumption. These small-form-factor PCB modules are the smallest LoRaWAN modules on the market with a built-in MHF4 connector. The modules can easily be programmed with the company’s AT command set in hosted mode, employing an external microcontroller. In hostless mode, it uses its powerful Cortex-M33 core with Silicon Labs’ Simplicity Studio to allow users to write their own application using C or take advantage of sample applications and radio certifications the company offers. The series also includes LoRa Point to Point (LoRa P2P) capability, permitting users to create their own private, long-range, point-to-point radio network between two modules. With an integrated TCXO, the series provides superior performance across industrial temperature ranges of -40C to +85C, while the onboard components complete a DC-DC converter supply ultra-low power consumption.

Together with the company’s FlexPIFA and i-FlexPIFA antennas, available for 868MHz and 915MHz frequency bands, the series modules provide developers the flexibility for rapid integration into space-constrained LoRaWAN applications. The antennas are flexible, adhesive-backed antennas available in MHF1 and MHF4L connector options, designed with the radiating element facing outward for flexible mounting options. These inverted flexible planar F-type antennas are ideal for sub-GHz applications, delivering consistent and reliable connection performance across the 868MHz and 915MHz ISM bands.
