The WLR089U0 is a Long Range (LoRa) transceiver module for the sub-1GHz ISM bands such as 868 MHz (Europe) and 915 MHz (North America), optimized for ultra-low-power applications. This module combines the ATSAMR34J18B SiP (System-in-Package), 32.768 kHz crystal, 32 MHz TCXO, RF switch, lumped element harmonics rejection filter, impedance matching circuits, Low Pass Filter (LPF) and required RF shielding in a compact 17 mm x 13.5 mm design. The module supports LoRa® and FSK modulation.
The LoRa technology is a spread spectrum protocol optimized for low data-rate, ultra-long range signaling. It is ideal for battery-powered remote sensors and controls. The module also includes USB, making it suitable for USB dongle applications or for software updates via USB.
