Microchip Technology WLR089U0 Low Power LoRa® Sub-GHz Module

Microchip WLR089U0 Low Power LoRa® Sub-GHz 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 256KB of Flash and 40KB of SRAM (8KB battery-backed) in a compact 17mm x 13.5mm package. With ultra-low power sleep currents as low as 790nA, the Microchip WLR089U0 modules are ideal for battery-powered remote sensor applications.

The highly configurable module peripherals include up to four SERCOMs (configurable as I²C/SPI/UART/LIN interfaces) with one in the low power domain, seven 12-bit ADC channels, and two analog comparators. The module supports LoRa, FSK, MSK, and OOK modulations and delivers up to 18.6dBm TX power with an RX sensitivity down to -136dBm.

The module operates from 863MHz to 928MHz 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.
