iM880B-L LR_Base - Long Range Radio Module

The 'iM880B-L LR_Base' 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 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. Even when reducing the output power to +14 dBm ranges beyond 12 km are feasible in free space (Line of Sight). The  'iM880B-L LR_Base' is pre-certified according to the European RED guideline and can be soldered like an SMD component.

The 'iM880B-L LR_Base' includes an embedded protocol stack which allows the setting of six orthogonal spreading sequences, four error correction schemes and three signal bandwidths and thus offers the user a high degree of flexibility. Furthermore it provides various options for configuration and communication via the serial interface. In addition, it is possible to integrate customer specific applications on request.

The Radio Module is pre-programmed with LR_Base, a propritary protocol.
