SK-iM282A – Long Range Radio Starter Kit

The Starter Kit is a plug & play solution to explore the features and capabilities of the Long Range Radio (LoRa®) module iM282A. 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.


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 (LoRa)

The WiMOD LR Studio is a Windows application which allows to explore the capabilities of the IMST LoRa® module, an ultra-low-power, high-performance, pre-certified Long Range radio module. The Windows GUI offers a comfortable way to configure and control the features of the embedded WiMOD Radio Stack.

WiMOD_LR_Base_Plus_Feature_Spec_V1_1pdf This document outlines the WiMOD LR Base Plus firmware features. This firmware supports the following radio WiMOD LR radio module iM282A
WiMOD_LR_Base_Plus_HCI_Spec_V1_2.pdf Host Controller Interface specification. The WiMOD LR Base Plus 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 Base Plus firmware provides several services for configuration, control and radio link access. This file contains the current WiMOD LR firmware (hex-file) for iM282A. 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 iM282A. This tool is intended to be used for the first steps of implementing the HCI interface between the radio module and the host MCU. It is a basic tool for checking if the basic communication primitives are working. It generates the packets in raw format of the HCI interface. This file contains a “C++” implementation of LR_Base_HCI interface
