Microchip WLR089U0 LoRa module

The WLR089U0 module is an ultra-low-power, regulatory certified LoRa module based on the ATSAMR34J18 LoRa IC.

This standalone module includes a 32-bit Arm^® Cortex^®-M0+ processor and offers 256 KB of Flash and 4 0KB of SRAM (8 KB battery-backed) in a compact 17 x 13.5 mm package. With ultra-low power sleep currents as low as 790 nA, the WLR089U0 modules are ideal for battery-powered remote sensor applications. 

The module operates from 863 to 928 MHz and is FCC, IC and RED certified. Supported by WLR089 Xplained Pro Evaluation Kit (EV23M25A). These modules highly accelerate the time to market for LoRa end-nodes. 

Key features

• Ultra-low power LoRa module
• Standalone module with 256 KB flash and 40 KB RAM
• 863 to 928 MHz dual-band coverage
• FCC, IC and RED certified

Additional features

• The highly configurable module peripherals include up to 4 SERCOMs (configurable as I2C/SPI /UART/LIN interfaces) with one in the low power domain, 7 12-bit ADC channels, and 2 analog comparators. The module supports LoRa, FSK, MSK, and OOK modulations and delivers up to 18.6 dBm TX power with an RX sensitivity down to -136 dBm.
• The module operates from 863 to 928 MHz and is FCC, IC and RED certified. Supported by WLR089 Xplained Pro Evaluation Kit (EV23M25A), Atmel Studio, and a detailed module reference design package, these modules highly simplify the development and accelerate the time to market for LoRa end-nodes.
