![](https://d2g2p0i8cc2bmh.cloudfront.net/2024-12/453-00139-K1-RENDER.94.png)
Overview
Now available: The LR 11 868MHz and LR 11 915 MHz click boards, powered by our RM126x modules!
The Ezurio RM126x series of modules (RM1261 and RM1262) is based on Silicon Labs EFR32 SoC and the Semtech SX126x radio. They provide a low power, long range solution for you to easily develop your LoRaWAN implementation. The RM126x series supports LoRaWAN classes A, B and C, and also includes a LoRa Point to Point (LoRa P2P) capability which enables you to create your own private ultra-long range radio network between two RM126x modules.
The RM126x series modules are small form factor PCB modules with a built in MHF4 connector, TCXO and a DC-DC converter. The module is designed to operate in both hosted and hostless modes.
- Hosted Mode – When connected to an external microcontroller, it can be simply and easily programmed with our AT command set.
- Hostless Mode – Utilizing the powerful Cortex-M33 core which includes 512kB flash and 32K of RAM. Full support is offered by Silicon Labs' Simplicity Studio for development purposes with a range of sample applications being offered by Ezurio to simplify customer development.
- Small Form Factor – 14mm x 13mm PCB module designed for compact IoT devices.
- LoRa P2P Communication – Enables you to create your own proprietary wireless network.
- Quick to market - Built in TCXO, DC-DC converter and on board MHF4 antenna connector.
- Ultra-Low Power Consumption - Years of use on a single battery.
- Qualified Ezurio Sub Ghz Antennas - Certified to work with Ezurio Sub-GHz FlexPIFA, Sub-GHZ i-FlexPIFA and Sub-GHz Flexdipole antenna.
- LoRaWAN Certified - RM1261 and RM1262 (Test Reports)
