[Introduction]：EWM104-BT09SP is a Bluetooth to serial port slave module based on Bluetooth protocol version 5.0 developed by Ebyte based on Tailingwei's TLSR8208BER chip. It is small in size, low in power consumption, and operates in the 2.4GHz frequency band. The Bluetooth module uses common AT commands to set parameters, and the operation is simple and fast. The module supports slave roles, Bluetooth broadcasting, data transparent transmission, and air configuration. The module can be widely used in smart wearables, home automation, home security, personal health care, smart home appliances, accessories and remote controls, automobiles, lighting, industrial Internet, intelligent data acquisition, intelligent control and other fields. It supports data transmission at a maximum baud rate of 1000000bps.
