[Introduction]：The E104-BT52X-V5.3 is a low-power Bluetooth module based on the dialog DA14535 chip, the BLE5.3 protocol, and the IPEX-3 antenna interface. It supports Bluetooth host, slave, master-slave, and observer modes, and AT command parameter setting. It also supports low-power broadcasting, data transparent transmission, and over-the-air configuration. It can be widely used in smart wearables, smart security, smart homes, industrial Internet, smart data acquisition, and smart control.
