RM126x Ultra-Low Power LoRaWAN Module

Under Development

Overview

The Laird Connectivity RM126x series of modules (RM1261 and RM1262) is based on Silicon Labs EFR32 MCU 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 Laird Connectivity 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 Laird Connectivity Sub Ghz Antennas - FlexPIFA and i-FlexPIFA antennas under development for use with RM126x.

FAQ

Installing and configuring REPO the easy way!

The repo tool is often available to be installed using a package manager. In the case you're facing challenges with this method, or would like to directly add the repo files to your path, the following commands can be used:

sudo wget https://storage.googleapis.com/git-repo-downloads/repo -O /usr/local/bin/repo
sudo chmod a+rx /usr/local/bin/repo

When you run the "repo init" command for the first time you will be asked to configure your name and email. You can also set these values with the following commands:

git config --global user.email "you@example.com"
git config --global user.name "Your Name"
git config --global color.ui true
