The iM880B-L from IMST GmbH is a compact and low-cost radio module that operates in the unlicensed 868 MHz band and the Indian 865 band and combines a powerful Cortex-M3 controller with the LoRa® transceiver SX1272 of Semtech Corporation. A sensitivity of up to -137 dBm and a maximum output power of +19 dBm result in a link budget of more than 156 dB.
The iM880B-L is a compact and low-cost radio module that operates in the unlicensed 868 MHz band and combines a powerful Cortex-M3 controller with the new LoRa® transceiver SX1272 of Semtech Corporation. A sensitivity of up to -138 dBm and a maximum output power of +19 dBm results in a link budget of more than 156 dB. Even when reducing the output power to +14 dBm ranges beyond 15 km are possible in free space.
The iM880B uses Semtech’s patented LoRa® modulation technique which combines spread spectrum modulation and forward error correction techniques to increase the range and robustness of radio communication links compared with traditional FSK or OOK based modulation.
Using the iM880B in an application minimizes the need for an expensive and time-consuming RF development. Fast time to market is possible with this pre-qualified module.
The iM880B-L can be ordered with a pre-programmed embedded protocol stack (iM880B-L_LoRaWAN):
It enables Low Power Wide Area Networks (LPWANs) for Internet-of-Things (IoT) and Machine-to Machine (M2M) applications and supports Activation By Personalization (ABP) or Over The Air (OTA) activation. It comes with the WiMOD LoRaWAN® HCI interface and allows easy configuration.
