USR-L101-H-C Serial to LoRa Module Introduce
Notes: This products has to be used with our gateway - 【USR-LG220-H】https://en.usr.cn/index.php?route=product/product&product_id=172
USR-L101-H-C supports LoRa concentrator communication protocol and can realize communication between user's serial device and LoRa converter. LoRa transmits/receives data by serial and it can lower the wireless application threshold.
