Brief Introduction
M190 series LoRaWAN module is integrated with LoRaWAN protocol stack, compatible with LoRaWAN specification (V1.0.2, Class A/C) released by LoRa Alliance, which supports the connectivity function for different devices. The module can support wide frequency:low band 470~510MHz or high band 862~932MHz.
M190 module uses ST® SOC STM32WLE5xx chip(integrated with LoRa SX1262 chip),has many features as low power, long range and high anti- interference etc, which can be used in many applications as smart metering, smart city and smart building etc。
Features
• Low power consumption: minimum standby current 3.5uA
• High sensitivity: up to -139dBm@SF12/125KHz
• High sensitivity: up to -139dBm@SF12/125KHz
• Support LoRaWAN Class A/B/C with integration of LoRaWAN protocol stack
• UART interface, stamp hole, support parameters configuration through AT command

What is your concern about?As the founder of the ICA Alliance, Alibaba has been in contact with many LoRa manufacturers both domestically and abroad. Comparing the overall performance of products such as quality control, scalability, and pressure resistance, Easylinkin is at the forefront of the industry. The after-sales service is also very good.
