[Introduction]：E105-BS21 module is a serial port to SLE (SparkLink Low Energy) module based on the SparkLink protocol version 1.0 and a PCB antenna interface. It has the characteristics of small size, low power consumption, long transmission distance, fast transmission speed, strong anti-interference ability, and low latency. It works in the 2.4GHz frequency band and has a maximum RF transmission power of 6dBm. The SLE module uses universal AT commands and is easy and quick to operate. The module can be widely used in smart wearables, home automation, smart appliances, accessories and remote controls, smart control and other fields.Send Inquiry
