LoRa Long Range Radio Lorawan Alliance Certified Starter Kits

SK-iM880B – Long Range Radio Starter Kit

The Starter Kit is a plug & play solution to explore the features and capabilities of the Long Range Radio module iM880B-L. The kit contains two demo boards and two radio modules soldered on specific adapter boards. The modules are pre-programmed with the Long Range Radio firmware.

Starter Kits


The demo board is the basic platform of the Starter Kit and provides several functional units. These units include power supply, USB interface, and several input and output elements, such as push buttons, DIP switches, potentiometer, and LEDs. In addition all pads of the attached radio module can be accessed via pin connectors.
Connection between the radio module and the demo board is established via a module-specific adapter board. The radio module is soldered on the adapter board which is attached to the demo board through pin connectors. The adapter board also has a SMA jack connected to the RF output of the radio module, which can be used to connect an external antenna (or RF measuring and test equipment).
By using the adapter boards all WiMOD radio modules can be attached to the same demo board. In that way an easy comparison between the modules is achieved to determine which one is the best for a target product. The adapter boards including the appropriate radio modules can be ordered separately to expand the Starter Kit.

WiMOD_LR_Studio_UserGuide_V1_3.pdf This document describes the WiMOD LR Studio, a Windows application which can be used in combination with the iM880B-L LoRa™ module.
WiMOD_LR_Base_HCI_Spec_V1_8.pdf Host Controller Interface specification. The WiMOD LR HCI protocol is designed to expose the radio module services to an external host controller. The communication between host and the radio (WiMOD) is based on so called HCI messages which can be sent through a UART interface. The WiMOD LR firmware provides several services for configuration, control and radio link access.
WiMOD_LR_ExampleCode_V1_1.zip This C++ example code project shows how to implement the WiMOD LR HCI (Long Range Host Controller Interface) Protocol on the host side. The code is implemented by means of Qt Creator (3.0.1) and the free available Qt framework (5.2.1). This project can be compiled for Windows / Linux and MAC OS X desktop operating systems.
WiMOD_LR_Studio_V1_18_4.zip The WiMOD LR Studio is part of the WiMOD Starter Kit. It is a plug & play solution to explore the features and capabilities of the Long Range module iU880B.
WiMOD_LR_Base_Firmware_V1_12.zip This file contains the current WiMOD LR firmware (hex-file) for the radio module iM880B-L and iU880B.

*Not yet supported by firmware, default interface is UART.
