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