Brief Introduction
M400 Series module based on LoRa spread spectrum modulation technology, providing TTL serial port and GPIO, built-in LoRaWAN protocol. The end products embedded in this module can be configured in a quick and easy way with gateways forming a star low power WAN (LPWAN) for ultra-long distance wireless data transmission。
Features
• Low power consumption: minimum standby current 5uA
• High sensitivity: up to -138dBm@SF12/125KHz
• Compliant with LoRaWAN Specification 1.0.2
• Support LoRaWAN Class A/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.
