adeunis ARF8240AA - johdollinen - harmaa - tasavirta - 6 - 30 V - 50 mm - 27 mm

IoT developers and system integrators deploying low-power wireless sensor networks can rely on the ADEUNIS ARF8240AA LoRaWAN transmitter module. This compact, surface-mountable module provides a wired pin-header interface and operates on a 6–30 V DC supply, making it suitable for industrial monitoring, smart metering, and environmental sensing applications.

Key specifications

• LoRaWAN connectivity supporting Class A, B, and C operation
• EU868 MHz frequency band (configurable for other regions)
• Wired interface via pin headers for easy integration
• Wide input voltage range: 6–30 V DC
• Grey housing with U.FL antenna connector
• Operating temperature range: -20 °C to 75 °C
• Max RF output power: +14 dBm (EU868)
• Ultra-low sleep current: 1.5 µA; peak TX current: 130 mA
• Supports LoRa and FSK modulation with AES 128-bit encryption
• CE certified for European compliance

Why choose it

The ARF8240AA combines robust LoRaWAN connectivity with a flexible power design, allowing it to be powered directly from industrial DC rails. Its low sleep current extends battery life in remote sensor nodes, while the U.FL connector enables antenna selection for optimal range. The module’s support for all LoRaWAN classes ensures adaptability to both uplink-heavy and downlink-critical applications.

Ideal use cases

• Smart building sensors (temperature, humidity, occupancy)
• Industrial equipment monitoring and predictive maintenance
• Smart agriculture and environmental data collection
• Asset tracking and logistics telemetry
• Utility metering (water, gas, electricity)

Good to know

The module is supplied as a bare board with pin headers for soldering or socketing. It requires an external antenna (U.FL connector) and a host microcontroller for configuration and data handling. The 6–30 V input range allows direct connection to common 12 V or 24 V industrial power supplies without additional regulation.
