SMA Antenna for iM891A-XL, iU891A (recommended)

Pigtail (cable) for antenna port of iC880A-SPI and iM891A-XL. u.fl-to-SMA female cable, length: 100 mm

The Lite Gateway (LGW) is a demonstration and evaluation platform consisting of the pre-certified concentrator iC880A-SPI, a Raspberry Pi, a pre-configured SD-card and a housing. The product requires an SMA-Antenna (868 MHz) and a Power Supply Unit (5 V, 2.5 A), see accessories. The Power Supply requires a 5.5mm/2mm barrel to connect the Lite Gateway Unit. This device enables LoRa-customers to demonstrate and evaluate LoRaWAN™ features, and can be easily connect to existing servers (e.g. iot.semtech.com , Loriot). The source code of firmware is provided by the open source github project lora-net) This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION OR EVALUATION PURPOSES ONLY and is not considered by IMST GmbH to be finished end - product fit for general consumer use.

The bundle iU891A-XL (includes USB-Stick and antenna) is a compact and cost–effective USB stick based on the Long Range Radio Module iM891A-XL that operates in the unlicensed 868 MHz band. It  supports all major unidirectional and bidirectional wireless M-Bus modes (S, C, T and combined C/T) with packet formats A and B as well as the OMS security modes 5 and 7. The bundle includes an external SMA-antenna, see article 404829. With an integrated +22 dBm power amplifier and a sensitivity of -149 dBm, a sensational link budget of approx. 170 dB can be reached. This makes the iU891A-XL an ideal solution for smart metering applications connecting water, heat, electricity and gas meters with data concentrators.

WiMOD Shield for Arduino™ - A Long Range Radio Extension Board for Ardunio™ The WiMOD Shield is a expansion board that enables users of Arduino™ / Arduino-compatible boards to use WiMOD radio modules based on LoRa™ technology. Arduino™ boards are microcontoller-based boards that allow the user to do simple designs and prototypes or experiment with microcontroller circuits in general. The boards offer an interface for extending the basic functionality like sensors and actors by just stacking the extension boards to the base board. The WiMOD Shield is a small and low cost extension board that can be attached to the top offering an radio interface based on the LoRa™ technology. The shield is an interface card for connecting a WiMOD radio module to an Arduino™ board. The Shield includes everything that is needed for connecting a WiMOD module to an Arduino™ board. The power supply is sourced by the Arduino™ board and the I/O logic levels are adjusted by integrated level shifters. The SMA connector offers the possibility to add virtually any suitable antenna to get a good performance. The Shield offers two possible UART connections, so it can be used with Arduino™ UNO-like board and with Arduino™ DUE-like boards. For the latter one an additional UART can be used exclusively for the radio module communication. Besides the hardware board a example software library providing an easy access to the WiMOD HCI interface is available. The library is compatible to the Arduino™ IDE an can be installed by a simple import of the given files. This makes a complete example showing all steps of processing WiMOD's HCI messages on the low level side. On the high level side the library offers a bunch of simple API commands that control the WIMOD modem firmware. Hence a prototype of a LoRaWAN™ end-node can be created in minutes. This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION OR EVALUATION PURPOSES ONLY and is not considered by IMST GmbH to be finished end - product fit for general consumer use.

The iC880A-SPI is able to receive packets of different end devices send with different spreading factors on up to 8 channels in parallel. Due to the fact that the combination of spreading factors and signal bandwidths results in different data rates the use of “Dynamic Data-Rate Adaption” becomes possible. That means that LoRa® nodes with high distances from the concentrator must use higher spreading factors and therefore have a lower data rate. LoRa-nodes which are closer to the concentrator can use lower spreading factors and therefore can increase their data rate. This allows to build easy to handle star or multiple star networks without the need of routers or repeaters. Note: To connect a SMA Antenna (i.e. Art. 404811) it requires an u.fl-to-SMA cable (Art. 404812). LoRaWAN™ is a trademark of LoRa Alliance™, LoRa® is a registered trademark of Semtech.
