iM980A-L - Long Range Radio Module

The iM980A-L is a compact and low-cost radio module that operates in the unlicensed 915 MHz band and combines a powerful Cortex-M3 controller with the new LoRa™ transceiver SX1272 of Semtech Corporation. A sensitivity of down to -137.5 dBm and a maximum output power of +17.5 dBm results in a link budget of more than 155 dB. The iM980A has received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Subpart C modular approval in accordance with Part 15.212 Modular Transmitter Statement about FCC.

The LoRaWAN protocol stack, specified by the LoRa Alliance, is based on IBM’s LMiC and IMST’s WiMOD-OS. It enables Low Power Wide Area Networks (LPWANs) for Internet-of-Things (IoT) and Machine-to Machine (M2M) applications and supports Direct or Over The Air Activation (OTAA). It comes with the WiMOD LoRaWAN™ HCI interface and allows easy configuration. Please refer to the download section.

WiMOD_LoRaWAN_EndNode_Modem_Feature_Spec_V2_9.pdf This document outlines the current version of WiMOD LoRaWAN® EndNode Modem firmware features.
This firmware supports the following WiMOD LoRaWAN® radio modules iM881A, iM880B, iM980A and iU880B.
WiMOD_LoRaWAN_EndNode_Modem_HCI_Spec_V1_26.pdf This document outlines the current version of the WiMOD LoRaWAN® HCI specification.
The WiMOD LoRaWAN® HCI protocol is designed to expose the radio module services to an external host controller. The communication between host and the radio is based on so called HCI messages which can be sent through a UART interface.

This file contains the current WiMOD LoRaWAN® firmware (hex-file) for  iM881A, iM880B, iM980A and iU880B . This version of the firmware has passed the LoRaWAN® certification process. It contains all necessary documentation and release information.

This is a GUI for easy configuration of LoRaWAN® compliant radio nodes. It supports Direct Activation and Over The Air (OTA) Activation, and provides the possibility to transmit unconfirmed and confirmed data.
It contains the current firmware for iM881A, iM880B, iM980A, iU880B and all necessary documentation and release information This tool is intended to be used for the first steps of implementing the LoRaWAN® HCI interface between the radio module and the host MCU. It is a simple tool for checking if the basic communication primitives are working. You can select LoRaWAN_HCI primitives with CRC and Slip encoding or in raw format. This C example code project shows how to implement the WiMOD LoRaWAN® HCI protocol on the host side. The project is created for IAR Embedded Workbench and uses an EFM32 microcontroller as host. This C example code project shows how to implement the WiMOD LoRaWAN® HCI protocol on the host side.
