USR-L100-C 是一个支持标准LoRaWAN 协议的低频LoRa 模块，工作的频段为：433Mhz 或470Mhz。
使用串口进行数据收发，降低了无线应用的门槛。它具有功率密度集中，抗干扰能力强的优势。LORA 直
序扩频技术将带来更远的通讯距离。
模块可以工作在1.8 ~ 3.6V，休眠模式下消耗电流仅2uA，满足电池供电需求，适合超低功耗的场合应
用。
模块的尺寸36.0mm x 21.0mm x 2.8 mm，采用SMT 封装，几乎可以满足所有用户应用中的对空间尺寸
的要求，例如M2M，数据传输系统等。(The alliance of LORA is an open, nonprofit member. It is considered that the association is now in the era of Internet of things. Our members work together, share experience, push LoRa's protocol, LoRaWAN's success, as an open global standard for security, operator level static connectivity. A certification program that ensures interoperability and flexibility in solving multiple Internet of things applications where they are still or moving. We believe that LoRaWAN can give everything a global sound.)
