This compact and rugged IoT module is built for seamless integration into field devices, offering LTE Cat-M1/NB2 connectivity with 2G fallback across a wide range of global frequency bands. It includes GNSS support through A-GPS, GLONASS, and GALILEO for accurate location services. Designed with a small, durable plastic casing (67 x 51.5 x 23.5 mm), it supports wall and DIN rail mounting and operates reliably in industrial environments with a temperature range of -30°C to +75°C.
The module features serial (RS232) and Micro USB interfaces, a wide input voltage range (6–24V DC), and a 1V8 SIM interface. It includes an SMA RF connector with 50Ω antenna impedance, 23 dBm typical output power, and secure boot functionality with pre-certified firmware. Compatible with Windows 7, Windows 8, Linux (ECM), and Android (RIL), it also supports cloud services, FOTA upgrades, and Semtech AirVantage IoT platform for remote device, application, and connectivity management. The module is RoHS-compliant and ideal for asset tracking, smart metering, industrial IoT, and remote monitoring applications.
