What are the key features of WLR089U0?
- Integrated SAMR34 ARM Cortex-M0+ MCU with LoRa transceiver achieving -148 dBm receive sensitivity
- Supports LoRaWAN Class A, B, and C at 868 MHz and 915 MHz with ultra-low 2 µA sleep current
- Pre-certified SMD module reducing time-to-market and eliminating need for separate RF design and certification
What is WLR089U0 used for?
The WLR089U0 is designed for long-range, battery-powered IoT deployments such as smart agriculture sensors, environmental monitoring stations, and industrial asset trackers that require multi-kilometer range with minimal power consumption. Its integrated LoRaWAN stack and -148 dBm sensitivity allow reliable communication through dense urban environments and across open fields up to 15 km. The pre-certified SMD module simplifies regulatory compliance in FCC and ETSI regions, accelerating product development for smart metering and supply chain tracking applications.

Frequently Asked Questions
What receive sensitivity does the WLR089U0 achieve, and how does that translate to communication range?
The WLR089U0 achieves -148 dBm receive sensitivity on its LoRa radio. In line-of-sight rural deployments this allows communication distances of up to 15 km, while in urban environments with building attenuation typical range is 2 km to 5 km, making it effective for city-wide smart parking or utility metering networks.
Which LoRaWAN operating classes and frequency bands does the WLR089U0 support?
The module supports LoRaWAN 1.0.2 Class A, Class B, and Class C operation on 868 MHz (EU) and 915 MHz (NA) ISM bands. Class A enables lowest 2 µA average sleep current for battery nodes, Class B adds scheduled downlinks via beacons, and Class C enables continuous receive for low-latency actuator applications.
How does the WLR089U0 module simplify regulatory certification compared to a discrete LoRa chip design?
As a pre-certified SMD module, the WLR089U0 carries FCC and ETSI approvals covering both the radio subsystem and antenna interface. A product using this module avoids full RF chamber testing, reducing certification cost by tens of thousands of dollars and cutting time-to-market by 4 weeks to 8 weeks compared to building a custom LoRa PCB design from discrete components.
