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. 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.

LoRa Applications Page >>

The RN2483 is a fully-certified 868 MHz module based on wireless LoRa® technology. The RN2483 utilizes a unique spread spectrum modulation within the Sub-GHz band to enable long range, low power, and high network capacity. The module's embedded LoRaWAN protocol enables seamless connectivity to any LoRaWAN compliant network infrastructure, whether public or privately deployed. The module is specifically designed for ease of use, which shortens development time and speeds time to market. LoRa technology is ideal for battery-operated sensors and low power applications such as IoT, M2M, Smart City, Sensor networks, Industrial automation, and more. The RN2483 is the first LoRa module to pass LoRa Alliance Certification testing. It is certified to the LoRaWAN 1.0.1 specification, ensuring that designers can quickly and easily integrate their end devices into any LoRaWAN network. Firmware Versions RN2483A-I/RM104 - LoRaWAN Specification 1.0.1, Ideal for Class A applications, Regulatory and LoRaWAN certified RN2483A-I/RM105 - LoRaWAN specification 1.0.2, Supports both Class A and Class C, Regulatory certified Microchip's complimentary and confidential Wireless Check online design review service is available for customers who have selected our products for their application design-in*. *The online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
