The WLR089U0-I/RM module from Microchip Technology 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 40 KB of SRAM (8 KB battery backed) in a compact 17 mm 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 highly configurable module peripherals include up to 4 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 18.6 dBm TX power with an RX sensitivity down to -136 dBm. The module operates in both European and North American ISM bands from 863 MHz 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 development and accelerate the time to market for LoRa end-nodes. The rich feature set of the WLR089U0-I/RM module makes it suitable for industrial, IoT, smart city, and any other low-power wireless applications.
