The iM880B-L from IMST is a Bi-Directional LoRa Module designed for the unlicensed 868 MHz band. Based on Semtech's ultra-long-range transceiver SX1272, it provides an output power of up to 19 dBm and has a receiver sensitivity of -138 dBm (SF 12; SB 125 kHz, CR 4/6). It offers an RF data rate from 0.24 to 37.5 kbps and has a LOS (Line of Sight) range up to 15 km. This compact module requires a DC supply of 2.4 to 3.6 V and draws 118 mA of Tx current, 11 mA of Rx current and 1.8 μA of current in sleep mode. It supports UART, SPI, and I2C interfaces and is certified with ETSI EN 300 220LoRaWAN standards. This device is available in a module that measures 20 x 25 x 3.3 mm and is ideal for Automated Meter Reading, Home and Building Automation, Wireless Alarm and Security Systems, Industrial Monitoring and Control, Long Range Irrigation Systems, IoT (Internet of Things), and Smart Cities applications.
